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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The Trump tariffs have been an outright failure nationwide. Tariffs amount to a $1,700 tax on each and every household in the United States. They have harmed U.S. business competitiveness and have cost the United States manufacturing jobs.
The Capitol Christmas tree is fully lit in DC! If you’re from #CA04 and are visiting DC during the holidays, please reach out to or stop by my office for a tour of the Capitol. We’re always happy to serve you.
