These are some of the most challenging times our ag community has faced in decades. The USDA reports California lost 400 farms in 2025, with 15,000 closing nationwide—one of the largest annual losses of the 21st century.
ince the sewage issues began, I’ve been in constant contact with local, state, and federal partners to push for solutions and secure every possible federal dollar to resolve this crisis.
Congrats to the Napa Valley Vintners on raising $3 million yesterday at Premiere Napa Valley. It was great to see the wine trade from all over the world come to Napa and support our wine community.
As an immigrant, Iraq War veteran, business owner, and as a Napa City Councilmember, Bernie has a long history of service to our country and our district, and he represents the best of our nation. I am honored to have him as my guest.
Telehealth is a proven way to meet patients where they are. I’ve long supported its ability to save time, lower costs, and save lives. For seniors and people with limited mobility, telehealth can be the difference between getting care and going without it.
On what would have been his 86th birthday, we honor my friend and colleague, civil rights icon Representative John Lewis. I was proud to join him during the 2016 House sit-in to demand action on gun violence and again in 2019 when the House passed universal background checks.
Thank you to everyone who came to my Sonoma Valley Office Hours. Whether you need help with immigration casework, passports, taxes, or navigating a federal agency, my team and I are here to help and to listen.
Honored to join Leadership Santa Rosa for their Government & Politics Day and spend time with young local leaders. We had a great conversation about public service, the work I’m doing in D.C., and how to be leaders for Sonoma County.
Nobody should be above the law. Crimes were committed in connection to Jeffrey Epstein, so prosecute them. More files exist, so release them. This is about justice for the victims. The American people deserve justice. Now.
Great to meet with the Putah Creek Council at Glide Ranch to learn more about their work restoring and protecting the Putah Creek watershed. Grateful for the leadership of Phil Stevens and their board as they connect our community to hands-on environmental stewardship.
@repgaramendi.bsky.social and I invited @repjimcosta.bsky.social to hear directly from the farmers, ranchers, and growers in our community about how this administration’s tariff and trade policies are impacting their livelihoods.
