Cycling is good for people and good for our planet. As Co-Chair of the Congressional Bike Caucus and as an avid cyclist, I introduced the America Bikes Act to improve and expand access to safe, healthy transportation for decades to come.
Proud to nominate seven local students to our nation’s top military service academies. Congratulations Isabella Hazel, Diego Rodriguez, Clare Cuneo, Charles Im, Owen Rainwater, Quinn Dixon, and Atticus Keys! Your hard work and dedication earned you this honor.
In Congress, the Gun Violence Prevention Task Force is leading the efforts to pass legislation that will protect our communities and help save lives. Every day, 100 Americans are killed by someone using a gun. Thoughts and prayers are never enough — gun violence demands action.
Congratulations to Jacobo and María Ángeles on their inspiring exhibition at Sonoma Botanical Garden. Your talent, craftsmanship, and commitment to preserving artistic traditions are evident in every stunning piece. Thank you for sharing your work with our community!
Good to see the court temporarily blocked the President’s political slush fund. I introduced legislation to impose a 100 percent tax on any payments from this fund because no insurrectionist or rioter should receive the hard-earned tax dollars of the American people.
Congratulations to Sutter Health for being recognized as the #2 large health system in our country. Thank you to all the doctors, nurses, caregivers, and staff whose hard work and dedication keep our community healthy.
Congratulations to the Sonoma County Superior Court on the opening of its new courthouse. The new courthouse will provide our community with the tools and space it needs to deliver justice for all.
Excited for the Napa Valley Grapegrowers’ breaking ground on their new Napa Valley Center for Grape Growing and Farmworker Education. This will be a great place to bring our community together.
Thank you to all the UC Davis students who joined our student town hall yesterday. It was great to join Chairman Aguilar and discuss affordability, federal funding cuts and student loan concerns with our next generation of leaders.
Congratulations to BiNational Health Alliance for another successful Napa Valley Latina Women’s Conference. This conference inspires amazing women throughout Napa County and provides resources for healthy living.
Thank you to Napa County Supervisor Liz Alesio, Yountville Cemetery Association and the Native Daughters of the Golden West for allowing me to speak at their Memorial Day event. Let us keep America's fallen service members in our prayers this Memorial Day weekend and always.
As founder and co-chair of the Congressional Wine Caucus, it’s great to recognize the 50th anniversary of the Judgment of Paris, a milestone that helped establish our Napa Valley wine community as a world leader in winemaking.
Researchers, students, and innovators at the University of California, Davis are working toward solutions for sustainable agriculture, climate resilience, and water conservation through the new Resnick Center for Agricultural Innovation.
My team and I are proud to serve #CA04! In April 2026, we closed 211 cases for constituents and recouped $326,050.57 in money owed to Fourth District residents. If you’re in need of help navigating a federal agency, please call my nearest office.
