16 years ago, we passed the ACA. Since then, I've heard from countless members of our community whose lives changed because of it. People could finally see a doctor, afford their prescriptions, and stop worrying about losing coverage.

I’ll be discussing the issues that matter most to our community, from protecting our democracy and holding this administration accountable to lowering housing and healthcare costs, addressing rising energy prices, and supporting our local wine community and small businesses hurting from tariffs.

TOMORROW at 5 PM I'm holding an in-person Ask Me Anything in Sonoma Valley! Come to Andrews Hall at the Sonoma Community Center and ask me anything.

This is a powerful reminder of just how much our neighbors give of themselves every single day. To every volunteer celebrated tonight: thank you. Our community is stronger because of you.

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

Proud to join the Sonoma Valley community at the 2026 Star Volunteer Awards to honor the incredible volunteers that make our community the wonderful place it is for all of us. More than 40 residents were recognized for their service to more than 40 local nonprofits.

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

But it is not enough to just remember, we must pass sensible legislation to ensure no more lives are lost and no more communities are shattered.

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

Five years ago today, a gunman took ten innocent lives at a King Soopers Supermarket in Boulder, Colorado. Today we remember every victim, including Officer Eric Talley who gave his life to protect others.

I will continue to defend the VRA and fight for every American’s ability to cast their ballots.

61 years ago, Martin Luther King, Jr. led thousands in a march from Selma to Montgomery to fight for the right to vote, leading to the passage of the Voting Rights Act of 1965. The right to vote is the basis of our democracy, never to be oppressed.

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

80 percent of maternal deaths are preventable. That’s unacceptable. Proud to cosponsor the Momnibus with @underwood.house.gov, Rep. Alma Adams, and @booker.senate.gov to save lives and support moms and babies nationwide.

It’s the job of the Director of National Intelligence to determine imminent threats to the United States. DNI Tulsi Gabbard says it’s up to the president. Why does she still have a job if Trump is doing it for her? www.nytimes.com/2026/03/18/u...

Harming police or service animals is already illegal under federal and state law. This bill would have added penalties if you’re an immigrant. Look at Kristi Noem if you want to further protect puppies.

DACA applicants who followed the rules, shared their personal information in good faith, and built their lives here shouldn't have their futures put at risk because this administration is keeping them from renewing their status.

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

The Trump administration is deliberately slow-walking DACA renewals, using bureaucratic delays as a backdoor to dismantle a program they couldn't end legally.

Senate Democrats Demand Answers for DHS ‘Slow-Walking’ DACA Renewals

Deferred Action for Childhood Arrivals recipients shouldn’t be at risk because of agency delays, senators wrote in a letter first shared with NOTUS.
