Mast's campaign website stated the following:

FIGHTING FOR CLEAN WATER & PROTECTING THE ENVIRONMENT

The most important issue for our community is the devastation of our water. This impacts everyone: businesses forced to close, people getting sick, animals killed, and our environment destroyed. Health and safety needs to be made a top priority to prevent these discharges. Our work in this area is not about one party or any individual; it is about defending our community by putting all people and our environment first.

Our accomplishments include:

Securing a commitment to authorize the EAA Southern Storage Reservoir

Passing hundreds of millions of dollars to combat harmful algal blooms, prevent toxic agricultural runoff and restore the Everglades

Fully funding expedited completion of the Herbert Hoover Dike

Passing legislation forcing the Army Corps to re-evaluate their discharge schedule

Passing legislation funding the development of technology to clean massive discharges of water

Serving as Vice Chairman of the Water Resources & Environment Subcommittee

MAKING HEALTHCARE MORE AFFORDABLE

There’s no doubt the rising cost of healthcare caused by Obamacare has burdened American families and created a massive increase in bureaucracy resulting in less choice. In fact, Martin and St. Lucie counties now have only one provider on the individual exchange. We need healthcare in the United States that increases choice and enables Americans to choose the doctors and plans that fit their specific needs, while still protecting individuals with pre-existing conditions and drastically lowering costs. We also need to eliminate red tape to speed up the development of life saving cures and drive down costs for prescription drugs. When reforming our healthcare system, we also must protect and improve care for seniors and veterans.

Our accomplishments include:

Eliminating Obamacare’s individual mandate tax

Securing a new law to lower prescription drug costs

Voting to decrease individual market premiums

Strengthening protection against fraud for Social Security beneficiaries

Passing legislation to expand affordable health coverage

Securing $6 billion to combat the opioid epidemic

Protecting Medicare benefits and voted to expand access to treatments through Medicare

Increasing support for Alzheimer’s patients

Increasing funding for cancer research

Extending the Children’s Health Insurance Program for 10 years

Writing a new law protecting health care benefits for veterans

ENSURING CARE FOR SENIORS

I will always protect Social Security and Medicare, ensuring our government keeps the promises it has made to current retirees and those planning to retire. I absolutely do not support cutting benefits for current retirees or anybody nearing retirement. In order to accomplish difficult objectives in times of crisis, I know that we must work together. So, I will continue to be a leading voice for addressing the critical solvency issue of Social Security and Medicare in a bipartisan way that protects care for seniors.

Our accomplishments include:

No cuts to Medicare

Passing legislation to strengthen Medicare

Voting to protect social security beneficiaries

Securing a new law to crack down on crimes targeting seniors

Protecting tax benefits for retirement savings

Writing a new law to protect benefits like nursing home care for veterans

Serving as a member of the Congressional Task Force on Alzheimer’s Disease

Increasing support for Alzheimer’s patients

IMPROVING CARE FOR VETERANS

Every Veteran who the VA serves must be treated as the most important veteran to ever be served. Anything less is unacceptable because every veteran who has sworn the oath, worn the uniform, and offered to give the last beat of their heart cannot not be taken for granted. That’s why I support giving veterans the flexibility to choose anytime, anywhere medical care and opened the first-ever office inside the West Palm Beach VA facility to provide on-the-spot support to veterans in our community. Veterans gave every American their best, and deserve the best care our nation has to offer.

Our accomplishments include:

Opening the first-ever Congressional office inside a VA hospital

Writing a new law protecting critical veteran’s benefits

Expanding Healthcare choice for veterans

Increasing access to GI bill benefits

Passing a new law to protect whistleblowers and increase accountability at the VA

BOOSTING THE ECONOMY

We must fight for working families by expanding opportunities and creating an economic environment that allows for job growth. The explosive growth of government regulations during the previous Administration hurt both economic growth and job creation. Making life work for families in our community starts with reducing government interference in every-day life, reducing government-imposed costs, and increasing individual liberty. Additionally, we must prioritize infrastructure projects, especially water infrastructure around Lake Okeechobee, to stop the devastation of our economy being caused by toxic water discharges.

Our accomplishments include:

Passing legislation requiring Congressional approval of new major regulations

Overturning more than a dozen overreaching Obama-era regulations

Investing hundreds of millions of dollars in South Florida water infrastructure

Securing a commitment to authorize the EAA Southern Storage Reservoir

Introducing legislation securing federal resources to support communities impacted by harmful algal blooms

Cutting taxes for American families, including doubling the standard deduction and child tax credit

CUTTING TAXES AND BALANCING THE BUDGET

Our current spending is unsustainable, which is why I’ve voted against irresponsible spending packages. We must pass a Balance Budget Amendment that will force government to live within its means. The tax cuts passed have allowed you to keep more of your money, stimulated the economy, and led to more investment. Now, we must continue working to close special interest loopholes and lobbyist-driven deductions, while making the individual tax cuts permanent.

Our accomplishments include:

Passing major tax cuts for American families

Doubling the child tax credit

Eliminating Obamacare’s costly individual mandate

Voting in favor of a balanced budget amendment to the Constitution

STOPPING BRIGHTLINE

I am 100% against Brightline (also known as All Aboard Florida). This is a vitally important issue in our community, as the train routes go right through the heart of our district without stopping. It would bring down property values, disrupt emergency responders, and with so many more proposed train routes, it’s going to put our children in increased danger going to and from school. Our town is against it, our environment is against it, and I’m against it.

Our accomplishments include:

Forcing Brightline executives to testify before Congress

Initiating a Department of Homeland Security study into Brightline’s plans

Exposing Brightline’s lies and abuse of taxpayer dollars

STRENGTHENING NATIONAL SECURITY AND REBUILDING OUR MILITARY

As a former combat soldier based in Afghanistan, I have seen the enemy face to face. I also know the war we are in is not only a war of military force; it is a war of ideology. ISIS seeks to destroy western civilization, and our very way of life. President Obama’s half-hearted, inconsistent policy failed, which is why we are working to quickly rebuild our military and put our troops on the front line in the best possible position to succeed.

As a Member of the Foreign Affairs Committee, I know we must also work to combat aggression from Iran, North Korea, Russia, and other adversaries who work to undermine global security. I strongly opposed the Iran Nuclear Deal and commend President Trump for withdrawing from it. That’s why I’ve voted to institute new sanctions on Iran, as well as North Korea and Russia. Moreover, Russia’s attempts to sow discord in the American electoral process must not be tolerated and must be met with a strong response to protect the foundation of our democracy.

Our accomplishments include:

Passing increased funding to rebuild our military

Increasing troop pay

Passing new sanctions on Iran, Russia and North Korea

Increasing cooperation between Israel and the United States for missile defense

Strongly supporting withdrawal from the Iran Nuclear Deal

SUPPORTING OUR ALLY ISRAEL

As a strong supporter of the state of Israel, I believe we must continue to repair the U.S. – Israel Relationship that was strained under the previous Administration. It was a great honor to volunteer alongside the Israeli Defense Force (IDF) following my service in the Army because the United States and Israel share common values like freedom and respect for human dignity. As a member of the Foreign Affairs Committee, I have worked to oppose the dangerous BDS movement, support Israel’s efforts to counter instability in the Middle East, and prevent a nuclear-armed Iran.

Our accomplishments include:

Introducing legislation to combat radical Islamic terrorism

Passing legislation to cut off U.S. aid funding being used to reward anti-Israel terrorists

Increasing U.S. – Israel joint missile defense activities

Increasing sanctions on Iran

Working to combat the Boycott, Divestment and Sanctions movement

Strongly supporting withdrawal from the Iran deal and recognition of Jerusalem as the Capital of Israel

Serving as a member of the Bipartisan Task Force to Combat Anti-Semitism

Participating in a Congressional delegation to Israel

SECURING THE BORDER & FIXING IMMIGRATION

We all know our immigration system, illegal and legal, is broken. For far too long, politicians in Washington haven’t had the will to fix it. For starters, we must secure the border and prevent visa overstays. We must also reform our legal immigration system to end arbitrary policies that continue to hurt our economy so we can be welcoming to those who want to be in the United States and follow our laws. The time is long overdue for Congress to lead on this issue by fixing the crisis on the border, defunding sanctuary cities, providing a solution for DACA recipients, and strengthening the rule of law.

Our accomplishments include:

Voting for legislation that would fund completion of a border wall

Voting to provide legal certainty to DACA recipients

Voting to end the separation of children from their parents at the border

Voting to end chain migration and the visa lottery program

Voting for legislation to defund sanctuary cities

Voting for legislation to implement E-Verify nationwide

DEFENDING THE SECOND AMENDMENT

I have carried a rifle and a pistol for most of my adult life and fired both in defense of every American and myself. The right to defend ourselves is God-given. It is not a right provided to us by our federal government, but rather, the right to keep and bear arms is a right the federal government is sworn to protect. I will continue to uphold the oath I took to support and defend the Constitution of the United States against all enemies, and I will fight to protect our Second Amendment from all attempts to erode it.

Our accomplishments include:

Passing legislation to protect the 2ndAmendment rights of concealed carry permit holders

Strengthening background checks without infringing on 2ndAmendment rights

WORKING FOR SAFER COMMUNITIES

I see my mission in Congress the same way I saw it in the military: keeping Americans safe. That’s why I’ve made community safety, health, and strength top priorities during my time in Congress. That means equipping our local law enforcement with the support they need to fight crime, prevent terrorism, reduce gun violence, stop domestic violence, prevent opioid overdose, and much more. This often takes hard, bipartisan problem solving, but the fact is Members of Congress aren’t elected to just make easy votes. We must act now to save lives by reducing violence.

Our accomplishments include:

Increasing funding for school security

Securing $6 billion to combat the opioid epidemic

Passing legislation to strengthen background checks

Supporting commonsense legislation to reduce gun violence

Passing several new laws to prevent sex trafficking and increase support for survivors of domestic violence or other sexual abuse

Passing more than 50 bills to combat the opioid epidemic

DEFENDING LIFE

As a father of three beautiful children with a fourth on the way, I’m a strong supporter of the right to life. I believe we must defend life at every stage and protect the most vulnerable members of our society. After serving in the Army for more than 12 years, I know what it means to protect life and see life lost. Our priority should always be to protect the innocent.

Our accomplishments include:

Passing legislation to protect the unborn

Voting to prohibit taxpayer funding for abortion

Voting to increase protections for infants born alive after a failed abortion procedure

MAKING EDUCATION WORK FOR EVERYBODY

Washington should not be mandating curriculum for states. On the contrary, each state should be a laboratory for innovation so states compete with each other for the best results. School choice is a very important issue for me, and I will continue advocating for dollars to follow students so parents can decide which school is best for their children.

Our accomplishments include:

Overturning Obama-era regulations imposing federal standards on local schools

Improving career and technical education policies to help more students compete for in-demand jobs

Passing legislation increasing accessibility of job training and skills development programs

Increasing access to G.I. Bill benefits for veterans

INCREASING ACCOUNTABILITY

Washington, DC wastes far too much money on programs that either don’t work, have outlived their usefulness, or should never have existed in the first place. Members of Congress love to create programs, but they don’t spend much time checking to see if taxpayers are getting their money’s worth. I pride myself on being a taxpayer watchdog and supporting efforts to make the federal government more efficient, effective, and accountable.

Our accomplishments include:

Cutting taxes

Voting for a Balanced Budget Amendment to the Constitution

Eliminating costly Obama-era federal mandates

Eliminating an unaccountable Obamacare board with power to cut Medicare payments

Supporting term limits for Congress

Passing a new law to protect federal whistleblowers

Voting to prevent Members of Congress from using taxpayer dollars to cover up workplace harassment[14]
