We should be in DC lowering costs for American families and putting safeguards on AI—not getting sent home because @SpeakerJohnson doesn’t want a vote on them.

Ho Yin Mo is a steadfast public servant who has been helping Bay Area residents access essential health care, child care and food assistance programs. His unnecessary detention is keeping him away from the communities he serves and those who care about him. Ho Yin Mo is my constituent and I am working closely with Assemblymember Stefani to help bring him home to the Bay Area where he is deeply missed. DHS is arresting and detaining people who are following our immigration process simply to fulfill Trump’s senseless quotas, and is consequentially hurting many law-abiding immigrants who are living and working here legally. These types of unnecessary detainments are costing families and communities dearly, and it is un-American. I will continue to exercise oversight over DHS and ensure our communities are safe.

All lethal guns should be treated like guns. That's why I introduced Garrett's Law, in honor of my constituent, to ensure lethal airguns are properly regulated.

Just two weeks after more than 40 parents and family members came to DC to demand action against nitrous oxide abuse, my bipartisan Nitrous Oxide Safety Act passed committee. This is what advocacy can accomplish. I’ll keep pushing until this dangerous product is off our shelves.

Happy Constitution and Citizenship Day! Today, we celebrate those born in America and those who choose to become American. It was inspiring to celebrate San Mateo adult school graduates a few months ago and witness their journeys toward citizenship and a new future here.🇺🇸

Hispanic Heritage Month is an opportunity to celebrate the traditions and achievements of Hispanic Americans and recognize the many ways they have shaped our nation. This month and always, we celebrate the diversity and contributions that make our communities stronger.

Ever wondered what it's like to intern in our District Office? From helping constituents with casework to supporting the Congressman at events across San Mateo County, our interns get a firsthand look at what it takes to serve our community.

ICYMI: I recently hosted an in-person town hall where I engaged directly with my constituents and discussed my top priorities when the Democrats regain the gavels this November among other issues. Watch the full discussion here: piped.video/watch?v=w1x90PII…

On the 25th anniversary of the September 11th attacks on the World Trade Center, I visited the @SMCFireDept where we paused to remember those we lost and honor the the survivors, first responders, servicemembers, and families whose lives were forever changed. We will never forget the courage and sacrifice of those who answered the call.💙

Did you believe this deepfake? Generative AI makes misinformation easier to create—and harder to spot. That’s why I’m leading lawmakers to ask for transparency from Meta on its rollback of key safeguards. Read more at kevinmullin.house.gov/2026/0…

Trump is blatantly trying to buy your vote – this is a total scam that he doesn’t have the power to do, would cost taxpayers over $1 trillion, and exacerbate the national debt that he’s already exploded. The economy is in turmoil because of Trump and Republicans, Americans need real solutions not empty promises. apnews.com/article/trump-div…

Congratulations to the @smplibraryfndn on celebrating the 20th Anniversary of the Main Library! At a time when access to reliable information and literacy are more important than ever, libraries give everyone a place to learn, stay informed, and connect with their community. I’m proud to see that work thriving here in San Mateo📚

This Labor Day, we celebrate the workers whose dedication keeps our communities and our country moving forward. We must continue pushing for fair wages, strong worker protections, and an economy where every worker has the opportunity to build a better, more secure future.

What actually makes a DC internship unforgettable? I asked our summer cohort to share their favorite spots outside of the office. Here's what made the cut...

This week, I voted to support a bipartisan, temporary federal spending plan that will prevent another government shutdown, not give another dime to ICE or CBP, and continue essential services working Americans depend on.
