Thank you to the Calistoga Chamber of Commerce for hosting this year’s tractor parade! I was blown away by all the entries this year and I’m so happy to have been invited to be a judge again. Always a blast celebrating our rich agricultural heritage during the holiday season.

Rep. Mike Thompson@mikethompson.house.govDec 7(source)

Proud to join the Napa community for the 61st Annual Holiday Parade. Thank you to everyone who makes this tradition so special year after year. Wishing all a joyful and peaceful holiday season.

Rep. Mike Thompson@mikethompson.house.govDec 7(source)

A great morning in American Canyon kicking off the 15th Annual Reindeer Run! Loved cheering on all our runners. Thank you to the American Canyon Community and Parks Foundation for all they do to keep everyone active and connected.

Rep. Mike Thompson@mikethompson.house.govDec 7(source)

As a veteran, I know the hardships of war. On Pearl Harbor Remembrance Day, we honor the lives lost in the attack on Pearl Harbor and reflect how our nation came together to help end World War II and build a more peaceful future.

Rep. Mike Thompson@mikethompson.house.govDec 6(source)

I’ve spent years fighting to close loopholes and make sure big corporations pay what they owe.

Rep. Mike Thompson@mikethompson.house.govDec 6(source)

Billion-dollar corporations shouldn’t get tax loopholes to dodge paying their fair share. That’s why I joined @beyer.house.gov and @warren.senate.gov in urging the Treasury Department not to weaken corporate tax rules.

Congratulations to the new hires and all those honored at the Solano County Sheriff's Office Recognition and Oath of Office ceremony. Thank you for your commitment to keeping our communities safe. www.thereporter.com/2025/12/05/s...

Thank you to Larry Kamer for the invitation to speak with members of our community who joined his class. It was great to share an update on my work and meet so many neighbors who care deeply about our country.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

I’m proud to see this kind of innovation taking root right here at home, and I look forward to all the ways it will support our growers and strengthen our agricultural future.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

Congratulations to Sonoma County Winegrowers and Reservoir on breaking ground on California’s first ag-tech startup incubator for vineyards.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

If this administration truly wants to Make America Healthy Again, we need to stick with the science.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

Hepatitis B vaccines for infants have been standard practice for over 30 years and they’ve reduced the rates of liver diseases caused by Hep B by 99 percent. Protecting children from health risks should be common sense and it’s been proven that these vaccines work.

CDC advisers vote to overturn decades-long policy on hepatitis B vaccine for infants

In a controversial move, the vaccine advisory group reversed a recommendations for universal immunizing of newborns intended to protect them from a virus that attacks the liver.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

Secretary Hegseth is threatening to cut support for the Scouts. That’s wrong. Scouting teaches discipline, responsibility, and real-life skills. Using a youth development program as a political wedge is disgraceful.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

Congressional Republicans need to work with Democrats to extend ACA premium tax credits and lower costs for Americans.

Rep. Mike Thompson@mikethompson.house.govDec 5(source)

Americans who continue to see rising costs everywhere in their lives can’t get ahead, and the American Dream is deferred. If we’re serious about building a better America for current and future generations, we can’t allow health insurance costs to skyrocket.

Rep. Mike Thompson@mikethompson.house.govDec 4(source)

Congratulations to Chief Fabio Rodriguez on becoming Napa’s new Chief of Police. With decades of experience and a strong record of community engagement, he’s the right leader for this moment.

Rep. Mike Thompson@mikethompson.house.govDec 4(source)

Congressional Republicans have an opportunity to work with Democrats to lower costs for Americans. I urge Speaker Johnson to shift his focus away from billionaire donors and deliver for everyday Americans who are paying too damn much every time they turn around.

The best way to improve America’s global competitiveness is to stop kneecapping our own workers and businesses with Trump’s tariffs. @mikethompson.house.gov:

Rep. Mike Thompson@mikethompson.house.govDec 4(source)

This president's tariffs on steel, lumber, and other building materials act like a housing tax, driving up construction costs and making our affordable housing shortage even worse. If we want to build more housing to address that shortage, tariffs are only making the problem worse.

Rep. Mike Thompson@mikethompson.house.govDec 3(source)

Tariffs don’t just raise the price of imports—they drive up the cost of American goods too. When the price of a Mexican avocado goes up, the California avocado does too. Families are already struggling with high grocery bills, and these tariffs are a massive consumer tax.
