Joined my colleagues in protesting the Trump Administration’s plans to destroy D.C.’s 15th street bike lane. It was a big win yesterday when a judge ruled that the Administration cannot proceed with their plans to destroy the beautiful route that over a million cyclist use yearly.

Thank you to the families of gun violence victims who put together the powerful “30 Under 30, 30 Victims of Gun Violence Under the Age of 30” magazine. These families carry their loss with them everywhere they go. We must remain committed to passing sensible gun violence prevention legislation.

Happy #EarthDay! For fifty-six years, we have celebrated this day to raise awareness for environmental issues and inspire action. As a life-long conservationist, I have and will continue to fight for our environment!

Rep. Mike Thompson@mikethompson.house.govApr 22(source)

RFK Jr’s so-called Make America Healthy Again crusade has accomplished nothing but making preventable diseases deadly again.

Rep. Mike Thompson@mikethompson.house.govApr 22(source)

This Administration’s choice to overturn one of our most important environmental protections is devastating. Without the ability to regulate greenhouse gas pollution, it will be even harder to protect our environment from climate change. www.theregreview.org/2026/04/21/a...

EPA’s Repeal of the Endangerment Finding Will Cost Society | The Regulatory Review

EPA’s lopsided focus on regulatory costs ignores the much larger forgone benefits and the law.

Proud to have secured $3.15 million for the Habematolel Pomo of Upper Lake Tribe to build a community center providing educational and workforce training opportunities, meeting and event spaces, and partnership programs that will serve the entire Lake County community.

Rep. Mike Thompson@mikethompson.house.govApr 21(source)

Rooting out fraud and holding those who commit it accountable is important. It's unacceptable that the President pardoned fraudsters who committed more than $1.6 billion in Medicare and Medicaid fraud.

Rep. Mike Thompson@mikethompson.house.govApr 20(source)

Great to join local leaders and ride in another successful Picnic Day Parade. There’s nothing better than bringing people together at the largest student-run event in the nation to celebrate our communities, local businesses, and the work of UC Davis students and professors.

27 years ago, 13 people were senselessly killed at Columbine High School. Today, we hold the Columbine community close and remember their legacy. We must continue our work to pass sensible legislation to keep firearms out of the hands of people who are a danger to themselves or others.

Rep. Mike Thompson@mikethompson.house.govApr 19(source)

Great to join Napa Earth Day to celebrate our planet! Climate change is one of the most pressing issues facing us, and I will continue to work to conserve our beautiful lands, lower emissions, and protect our planet.

This National Volunteer Month we celebrate our friends and neighbors volunteering to help our communities and country. Thank you to everyone volunteering to provide essential services and transform our world for good.

Simple, everyday conversations help shape how future generations understand saving, protection, and long-term planning. Expanding access to financial education early in life is essential to building lasting financial confidence. #FinancialLiteracyMonth

Congratulations to all of the winners for being recognized for your contributions to labor, including the Napa County Board of Supervisors for being named the 2026 Mike Thompson Legislator’s Legacy Award Winner! (2/2)

Rep. Mike Thompson@mikethompson.house.govApr 18(source)

Congratulations on this year’s 16th Annual Napa-Solano Central Labor Council Spring Salute! A strong workforce is the backbone of our economy, and hard-working men and women like the members of the Napa Solano Central Labor Council keep our community moving. (1/2)

Americans deserve health policies grounded in evidence and science. Instead, we have RFK Jr. and this President elevating misinformation and undermining basic public health. Enough is enough. abcnews.com/Health/rfk-j...

RFK Jr. spars with House Democrats over vaccine policies amid rise in measles cases

Democrats on the House Ways and Means Committee seized on public health policies enacted under Health Secretary Robert F. Kennedy Jr.

Great to meet with Chico State President Steve Perez. Proud to be a CSU alum and to work with students, faculty, and administrators to help lower higher ed costs and make education more accessible.

Rep. Mike Thompson@mikethompson.house.govApr 16(source)

Today, my thoughts are with the friends and families of those lost and the entire Virginia Tech community. We must continue to work to reduce gun violence and help keep our communities safe. (2/2)

Rep. Mike Thompson@mikethompson.house.govApr 16(source)

19 years ago, 32 people were murdered and 23 were injured at Virginia Tech during one of the worst mass shootings in our country’s history. (1/2)

Rep. Mike Thompson@mikethompson.house.govApr 15(source)

Today is Tax Day, and millions of hardworking Americans are feeling squeezed. This administration promised tax relief to working people. Instead, they delivered massive tax cuts to wealthy donors and big corporations and gave a fraction of what was promised to everyone else.

How Trump's tax law boosts the wealthy and leaves behind some workers he promised to help

President Donald Trump pledged “no tax on tips, no tax on overtime, no tax on Social Security.” For some who are filing their taxes this year, the reality is different.

Rep. Mike Thompson@mikethompson.house.govApr 15(source)

Four million miles and counting! Got to sit in the cockpit to get my certificate before returning to my regular Row 20 bulkhead seat. I fly home from Washington every week to meet with local leaders and hear directly from members of our community. It’s the only way to do this job right.
