Campaign websiteBiss' campaign website stated the following:Rebuilding an Economy that Works for EveryoneOver the past four decades, the entire American economy has stopped working for regular people. A few giant companies now control our food, our health care, technology, consumer goods, and entertainment. Corporate consolidation causes higher prices for consumers, lowers wages for workers, crowds out local small businesses, and makes our economy less innovative. This consolidation isn’t happening by accident – it’s the result of deliberate choices that have been made by both Republicans and Democrats.Unchecked corporate power isn’t just hurting our economy – it’s killing our democracy. Corporate monopolies have too much economic power and too much political power. We need to stop monopolies from using their lobbying power to rig the system, rewrite the tax code for their own benefit, and remove basic protections for workers, consumers, and the environment.Restoring competition and unrigging our economy is existential for our country. We need to fight back against big oil to protect our environment. We need to go toe-to-toe with big tech to protect our privacy, our kids’ mental health, and our small business owners. And we need to take on big pharma and big insurance companies to make sure every American has access to high quality and affordable health care.In Congress, I’ll work to:Restore Federal Antitrust Enforcement: Donald Trump has stacked the federal agencies tasked with protecting competition – the Federal Trade Commission and the Department of Justice – with MAGA cronies and special interest lackeys. I’ll fight to restore independence at the FTC and DOJ to make sure we fully enforce our antitrust laws.21st Century Antitrust: Our central antitrust laws are more than 100 years old. It’s time to update our antitrust framework for the 21st century with legislation to empower our agencies to unwind anticompetitive mergers and to implement clear thresholds for when a merger grants a company too large a market share.Ending Wall Street’s Racket To Drive Up Costs: Hedge funds and huge private equity firms are buying up apartments buildings and single family homes, raising rents and increasing costs for families. I’ll work to pass the End Hedge Fund Control of American Homes Act to put a stop to this predatory practice.Supporting Small and Independent Businesses: Monopolies like Amazon make it impossible for small businesses to get ahead. We need to make sure that every small business can compete fairly with companies like Amazon that run giant marketplaces. And we need to make sure giant corporations pay their fair share.Cracking Down on Private Equity Abuse: From hospitals to nursing homes to grocery stores, giant private equity companies are buying up businesses and institutions we rely on, raising prices, cutting services, and taking advantage of workers. We need to crack down on corporate vultures and pass the Stop Wall Street Looting Act to make sure private equity firms can’t leave workers high and dry.Ending Corporate Welfare: This one is simple – no more tax breaks for multinational corporations that outsource jobs and exploit workers.Cap Credit Card Interest Rates: Credit card companies and big banks are trapping Americans in a never-ending cycle of debt with outrageous interest rates. There’s bipartisan support to cap credit cards interest rates. It’s time for Congress to get the job done and pass this legislation.Capping Student Loan Rates and Expanding Free College: We’ve trapped a generation of students under crushing student loan debt. Public college should be tuition-free and interest rates on student loans should be capped. When Americans pursue higher education, our whole country and our whole economy are better off. Empowering Workers to OrganizeFor decades, corporate profits have soared while wages for working people have stagnated. The gap between the ultra-wealthy and the rest of us keeps growing — yet people are working harder than ever and producing more than ever. Why? Because massive corporations and their union-busting leadership have systematically weakened the right to organize, dramatically shifting power away from workers.Union membership in the U.S. is near historic lows, and it’s not because workers don’t want to organize. Poll after poll shows strong public support for unions, but the law is stacked against them. Corporations exploit loopholes, illegally fire union organizers and activists, delay union elections, hold captive audience meetings to pressure workers, and use union-busting firms to intimidate workers without consequences. Meanwhile, tech startups and conglomerates regularly manipulate independent contractor designations to avoid minimum wage and workplace benefit requirements. As a result, power has shifted overwhelmingly from the shop floor to the C-suite, and millions of workers are left without a voice.When workers can come together and bargain collectively, they win higher wages, better benefits, safer working conditions. This is true for both union and non-union workers, who also benefit from the higher standards achieved through collective bargaining agreements. Unions are among the most effective tools we have to reduce inequality and build a strong middle class. They’re also essential to racial, gender, and economic justice — helping to close pay gaps and protect frontline workers.But the stakes go beyond individual workplaces. A healthy democracy depends on a thriving labor movement. When working people have real power, they can hold corporations accountable, demand a voice on the job, and win policies that benefit all of us.I’ll champion legislation that restores the right to organize and builds worker power, including:Passing the PRO Act: This landmark bill would make it easier for workers to form unions, ban employer interference, and hold lawbreaking companies accountable with real penalties.Protecting Public Sector Unions: I’ll fight back against attacks on federal employees, teachers, nurses, and other public servants by defending their right to collectively bargain.Expanding Sectoral Bargaining and Worker Representation: Promote policies that allow entire industries — not just individual workplaces — to set fair labor standards. And workers should have representation on corporate boards of large companies, giving them a say along with shareholders.Banning Captive Audience Meetings: End the practice of forcing workers to attend anti-union propaganda sessions and captive audience meetings. Illinois has banned these meetings, and Congress should act too.Raising the Federal Minimum Wage: $7.25 an hour is an insult to American workers. The federal minimum wage should be raised to $17 an hour and indexed to inflation.It’s time to put the power of the federal government back on the side of workers. I’ll stand shoulder to shoulder with the labor movement and fight for a future where every job is a good job, and every worker has a voice.Bold Action to Respond to the Climate CrisisAround the world, across the country, and right here in Illinois, we’re already experiencing the catastrophic effects of climate change. Deadly heat waves, flooded neighborhoods, poor air quality, and rising energy costs are now the norm. Just 100 companies are responsible for 71% of greenhouse gas emissions. The big oil companies have known about the risks their products pose – and misled the public about those risks – for decades. But, while working families, small businesses, and local governments are left to pick up the pieces, the corporations responsible for the crisis continue to profit without consequence. In Evanston, I led the charge to pass some of the boldest climate legislation in the country, moving to fully decarbonize large buildings by 2050 and reduce reliance on fossil fuels inside our homes. But far more action is needed.Climate change isn’t only an environmental issue, it’s an economic issue, and it’s a moral issue. Working-class communities and communities of color are often the most harmed by corporate polluters — and often have the fewest resources to rebuild from and prepare for disasters.We need to pass a Green New Deal to slash greenhouse gas emissions, create good union jobs, finish the transition to renewable energy, and build infrastructure that can withstand the climate crisis. And we need to make the polluters who caused this mess pay to clean it up.I’ll support legislation that ensures corporate polluters — not vulnerable communities and taxpayers — bear the cost of the crisis they created. That means:Enacting a Polluter Pays Climate Superfund: The largest corporate carbon emitters should contribute to a national fund to finance disaster recovery, climate adaptation, and renewable energy.Repealing Fossil Fuel Subsidies: Each year, fossil fuel already gets hundreds of millions in federal subsidies. Trump’s new budget makes the problem even worse, providing tens of millions in new subsidies for coal, oil, and gas. We need to level the playing field for renewable energy and end these subsidies.Holding Polluters Legally Accountable: We need legislation to fully empower states, tribes, and local governments to sue major polluters for damages to health, land, and infrastructure. And Congress needs to get to work to reverse the cuts Trump and Elon Musk made to the EPA, and to restore the EPA’s authority to regulate carbon emissions.Passing a Green New Deal and Reinstating the Climate Provisions of the Inflation Reduction Act: We need a Green New Deal to rapidly transition to clean energy, invest in vulnerable communities, and create good-paying union jobs. The Inflation Reduction Act was a giant step in the right direction, and we must pass a new budget bill to reverse Trump’s cuts to wind, solar, energy efficiency, and electric vehicle infrastructure.Investing in Vulnerable Communities: Any federal action on climate change must prioritize and invest in the neighborhoods and communities most affected by pollution and most at risk from climate change, especially minority and low-income communities.Fighting for our Future, not for Oil Companies’ Profits: We need to invest in our future, not outdated technologies and fossil fuel executives’ bottom lines. I’ll fight against federal authorization of new fossil fuel infrastructure and support regulatory changes that make it easier to build new renewable energy capacity.The climate crisis is already here, and we can’t keep letting the worst offenders off the hook. I've taken the No Fossil Fuel Money pledge because I’ll stand up to Big Oil, fight for clean air and water, and make sure the path to a green future is paid for by those who’ve profited from the status quo for too long.Cleaning Up Corruption and Restoring Trust in Our DemocracyAmericans are losing faith in our democracy – and with good reason. While our families struggle to get ahead, politicians in Washington line their own pockets and special interests and wealthy donors flood our political system with money to protect their own power and access. Donald Trump and his family are exploiting an already-broken system to the point of absurdity, cashing in on the presidency, pressuring businesses into sweetheart deals, and selling access to the highest bidder.But it isn’t just Trump — too many members of Congress are trading stocks, collecting dividends and campaign checks from corporations they’re supposed to be regulating, and profiting from corporate lobbying work after leaving office.Our broken campaign finance system rewards wealthy donors, drowns out our voices, and lets big corporations and their lobbyists write the rules. And when politicians are allowed to profit from inside information and make decisions that benefit their personal portfolios, we’re all left to deal with the consequences.The influence of big money in politics is at the heart of almost every problem our country faces. It’s why Congress refuses to take on Big Pharma, break up corporate monopolies, or act faster on climate change. We need campaigns powered by the people – not billionaires and corporate special interests.Restoring trust in government starts with making sure elected officials work for the people — not for donors, lobbyists, or their own investment interests.I’ll fight for reforms to clean up our politics and make our government truly accountable to the people, including:Ban Stock Trading by Members of Congress: I don’t own any individual stocks, and I pledge never to trade stocks while in Congress. We should end the practice of lawmakers profiting off non-public information and financial conflicts of interest. Members should serve the public — not their own portfolios.Passing the Government by the People Act: Create a small-donor matching system that lifts up grassroots contributors and reduces the power of big money in congressional elections. I led the successful effort to get this done in Evanston. We can and should do it nationwide.Stop Gerrymandering: Voters should choose their elected officials — elected officials shouldn’t get to choose their voters. I’ll champion federal legislation to ban partisan gerrymandering, and to ensure districts are compact, contiguous, and protect communities of interest. The recent Trump power grab to protect their Republicans’ House majority with mid-decade gerrymandering in deep red states is an undemocratic disgrace. While I fully support Democratic-controlled states’ moves to fight back rather than unilaterally disarm, we need a national ban on mid-decade redistricting.Ending Racist Voter Suppression and Restore the Voting Rights Act: We must fully restore the Voting Rights Act of 1965 and renew the federal government’s authority to review new voting laws in states with histories of racist voter suppression.Overturning Citizens United to Ban Unlimited Corporate Cash in Campaigns: The Citizens United decision is a blight that is killing our democracy. Corporations are not people. We need to amend the Constitution to get corporate money out of politics once and for all.Abolishing the Electoral College: The Electoral College is an 18th century relic that disenfranchises millions of Americans. It’s time to move to a national popular vote.Ending the Revolving Door: We should ban members of Congress and senior staff from becoming lobbyists immediately after leaving office.Strengthening Conflict of Interest Laws for the President and Vice President: Presidents and Vice Presidents should have to place their business and personal assets into a truly blind trust to ensure they cannot profit from their office.Codifying a Code of Ethics for Federal Courts, Including the Supreme Court: The Supreme Court must have a code of conduct, disclosure requirements, and a complaint procedure. An independent authority should be empowered to investigate public complaints and other potential violations. We also need a binding recusal process for federal judges so they can’t rule on issues where they have a conflict of interest, and we should ban federal judges from owning individual stocks.18-Year Term Limits for Supreme Court Justices: No comparable democracy in the world allows lifetime terms for top judges besides the United States. An 18-year term limit would reduce the partisanship of the court and promote healthy turnover.I’m not taking a dime of corporate PAC money, because the only people I’ll answer to are the people of the 9th District. I believe in a democracy where every voice matters equally, not just the ones with the biggest checkbooks.Combating Income Inequality By Taking on Wealth HoardingIn the wealthiest nation in history, millions of people can’t afford basic needs like housing, health care, child care, or retirement. At the same time, billionaires are getting richer than ever and multinational corporations are raking in record profits — all while paying lower tax rates than most Americans.This isn’t by accident. It’s the result of decades of deliberate policy choices and a corruption of the American tax code that has shifted wealth and power to the very top: tax cuts for the rich, deregulation for big oil and big banks, attacks on unions and the social safety net. Meanwhile, ridiculous loopholes — like the carried interest exemption — let hedge fund managers and private equity billionaires pay lower tax rates than the people who clean their offices.Working people are producing more than ever, but that wealth is being hoarded at the top. It’s time to rewrite the rules of our economy so that it serves the broad public, not the privileged few.We cannot sustain a society where the rich get richer and everyone else falls further behind. Extreme inequality isn’t just an economic issue, it’s a threat to our democracy, our society, and to the American dream itself.I’ll fight to close the wealth gap and make billionaires pay their fair share by:Implementing a Wealth Tax: In the United States, income inequality is at the highest levels in more than 100 years. And while working people pay their fair share, billionaires have carved themselves out of the tax code. We should implement a modest wealth tax on the assets of billionaires and ultra-millionaires to fund the priorities we all care about.Immediately Rolling Back the Trump Tax Cuts for the Highest Earners and the Trump Tariffs: Trump’s giveaways to the wealthy cost us hundreds of billions of dollars. We can and should immediately roll back Trump’s tax cuts for the richest people in the world. And we should get rid of Trump’s ridiculous tariffs, which are simply a tax on working people.Closing the Hedge Fund Loophole: End the outrageous carried-interest tax break, worth tens of billions of dollars, that allows private equity execs and hedge fund managers to pay lower tax rates than working Americans.Tax Billionaires’ Investment Income at the Same Rate as Wages: Income from stocks and capital gains should be taxed fairly — no more special treatment for the wealthiest Americans. Capital gains income should be taxed at the same rate as wages for anyone making more than $1 million a year.Raising the Corporate Tax Rate and Cracking Down on Tax Avoidance: We should reverse Donald Trump’s corporate tax cut and make multinational corporations pay their fair share. And we need to close loopholes that let corporations get rich off of Americans and then shift those profits offshore to avoid paying what they owe.Expanding Child Tax Credit and Earned Income Tax Credit: These middle class tax breaks have proven extremely effective at combating poverty, especially child poverty, and stimulating the local economy.Reinstating and Expanding IRS Direct File: No one should be charged outrageous fees simply to file their taxes. The IRS Direct File program was effective and popular — until it was killed by tax lobbyists looking to cash in on red tape. Direct File should be reinstated and expanded to all 50 states.I’m running for Congress because I believe our economy must reflect our values. That means hard work should pay off, no one should live in poverty, and billionaires should play by the same rules as the rest of us. If we want a future where everyone can build a life of dignity, we have to take bold action to close the inequality gap and invest in the common good.Lowering the Cost of Essentials — Putting Working Families FirstIn the 9th District and across the country, the cost of basic necessities is skyrocketing. Rent and home prices feel increasingly out of reach, especially for younger people. Child care costs more than a second mortgage. Health care premiums, deductibles, and prescription drug prices continue to climb. Utility bills continue to rise, and the spread of new data centers threaten to push prices even higher. But wages haven’t kept pace, and more families are being forced to choose between essentials like food, care, and medicine.When people can’t afford the basics, it holds the entire economy back. Parents leave the workforce because child care is too expensive. Seniors skip medication to pay the rent. Families are priced out of the neighborhoods they’ve lived in for generations.This isn’t just an affordability issue – it’s about who gets to live with dignity and stability, and who gets pushed to the margins. This is the wealthiest country in the history of the world, there is simply no reason why everyone shouldn’t be able to afford basic necessities and more.We must lower housing and child care costs, take on price gougers, and incentivize more development, especially near transit. It's past time we had a national single-payer health system such as Medicare for All providing universal coverage for all.I’ll fight for policies that bring down the cost of essentials and make sure working people can build a secure life, including:Lower Housing Costs for AllIncentivizing New Development: If we want to lower housing costs, we need to build more homes. The federal government can and should work to remove barriers to building, incentivize construction, and bring down the cost of buying and owning a home.Investing in Building Housing We Can Afford: Dramatically increase federal investment in building and preserving affordable housing through the Housing Trust Fund and Low-Income Housing Tax Credits.Ending Corporate Price-Gouging: Crack down on Wall Street landlords and private equity firms that artificially inflate rent and exploit housing shortages, including by banning the use of algorithms to set rent and by penalizing hedge funds and private equity firms that buy up single family homes.Supporting Renters and First-Time Buyers: Expand rental assistance and provide down-payment support for families shut out of homeownership.Prioritizing Federal Transportation & Infrastructure Funding for Pro-Housing Municipalities: Reward pro-housing zoning policies (like legalizing apartments near transit and lowering parking minimums) as a condition of receiving federal transportation grants.Reducing Administrative Burdens of Federal Programs: Streamline application and compliance processes, allow more flexible use of funds, and allow tax credits to pair more easily with other financing sources for federally supported housing initiatives.Universal, Affordable Child CareCapping Child Care Costs: Child care shouldn’t break the bank. I’ll fight for legislation to make sure no family spends more than 7% of their income on child care.Increasing the Child and Dependent Care Tax Credit for Inflation: The CDCTC, which tops out at just $3,000 for one child and $6,000 for two or more children, hasn’t been meaningfully changed in two decades, even as child care costs have exploded. By increasing the CDCTC significantly and making it fully refundable — a successful but temporary pandemic relief measure — we can immediately help families struggling to pay child care costs.Boosting the Child Care Workforce: Invest in higher wages, training, and benefits for early childhood educators to improve quality and expand capacity.Building a Public Child Care System: Create a nationwide network of high-quality, affordable child care centers — especially in underserved areas.Provide Universal Coverage Through Medicare for AllCreating a Medicare for All system: The health insurance system in our country is a mess. It’s expensive, impossible to navigate, and doesn’t lead to better health outcomes. We need to pass Medicare for All and deliver the affordable health care people enjoy in nearly every other advanced democracy.Rolling back Trump’s Medicaid cuts: The Republican budget makes deep cuts to Medicaid, ACA premium support, and hospitals across the country. Step one will be reversing these damaging policies immediately so working people can access care and hospitals can avoid closure.Capping Prescription Drug Prices: Expand Medicare’s power to negotiate drug prices and stop big pharma from price-gouging patients for life saving medicine, including expanding the IRA’s caps on out of pocket costs to private insurance.Ending Surprise Medical Bills: Strengthen laws to protect consumers from unexpected out-of-network charges and junk insurance plans.We must build an economy where people don’t have to scrape by just to keep a roof over their heads, send their kids to daycare, or fill a prescription. In Congress, I’ll work every day to bring down costs, raise wages, and make life affordable for everyone — not just those at the very top.Holding Big Tech AccountableAs social media platforms have completely changed how people live, their harmful consequences have become impossible to ignore. These platforms reward outrage and misinformation while burying truth and nuance, with catastrophic political consequences. Social media diminishes attention spans, distorts body image, and increases rates of anxiety and depression, especially among our children.Meanwhile, massive tech companies are collecting unfathomable amounts of data on all of us and using AI and other new technologies to surveil us and affect our lives in ways big and small. From the ads you see on TV to your ability to get a loan, big tech touches all of our lives without transparency or accountability. These companies have now weaponized their data and influence to dodge regulation, leaving them free to continue to manipulate markets and consumers worldwide. Illinois and other states have started to crack down on big tech, but we need federal action to address these issues.Whether it’s kids feeling crushed by online pressure, communities torn apart by disinformation, or our lives being manipulated by the whims of an algorithm, the stakes could not be higher.I’ll fight to rein in Big Tech and support legislation that safeguards mental health, protects children, and strengthens our democracy, including:Taxing Digital Advertising: There’s no reason why tech companies should be allowed to avoid paying taxes on the ad services they sell. I support a progressive tax on revenue from digital advertising that would help fund federal priorities and ensure big tech pays their fair share.Breaking up Amazon, Facebook, Google, and Apple: A few massive tech companies have cornered the market, harming competition and innovation. It’s time to pass an updated antitrust framework – and to fully use the antitrust laws we already have – to break up big tech. We should open up Amazon’s online marketplace, reverse Facebook’s merger with Instagram and WhatsApp, spin off Google’s purchase of YouTube, and tear down Apple’s “walled garden”. And no more allowing mega-mergers to create massive tech behemoths.Increasing Transparency and Data Portability: Our online data should belong to us – not big companies. That means we need laws that give us the right to see what data tech companies have stored about us, ask to have that data deleted, and bring that data with us to other sites.Banning Addictive Design for Kids: Social media companies are using algorithms to get our kids hooked. Congress should ban features designed to capture children’s attention spans and manipulate our kids – including “endless scroll” and “autoplay.”Age Limits and Parental Controls: We need to build on the Children’s Online Privacy Protection Act, raise the age where we allow data collection, and mandate real parental control tools to help parents protect their kids online.Fund School-Based Mental Health Services: Let’s invest in counselors, digital literacy education, and early intervention to combat the effects of social media on our kids.Restrict Cell Phone Usage in Schools: Cell phones have become a major distraction in our schools. Restricting the use of cell phones in classrooms will support teachers, students, and parents.Scientific Social Media Research: The Trump administration’s cuts to medical and scientific research funding needs make it harder to understand the effects of social media on our society – especially our kids. Congress needs to restore this funding and invest in better understanding this crucial topic.Algorithmic Transparency: Companies like TikTok build their algorithms to get users hooked – and might even be using their algorithms to promote a specific political agenda. Let’s force social media platforms to disclose how content is promoted and allow researchers access to study these algorithms. We have a right to know how these platforms are controlling what we see online.Crack Down on Bots, Deepfakes, and Election Interference: We need basic laws to stop the internet from becoming a tool to interfere in our elections and to spread misinformation. We should require platforms to strengthen safeguards against coordinated disinformation campaigns and online manipulation, including through bots and overseas “troll farms.”Rein in the Trump Administration and Executive PowerDonald Trump is a fool who thinks he’s a king. His outrageous executive actions, starting with allowing Elon Musk full access to the entire federal government, continue to violate the law and our civil rights. We need to rein in Trump — and any other future president — with clear, common sens
