It’s day 300 of the year, and there have already been more than 351 mass shootings in our country. We don’t have to live this way, and as Chair of the Gun violence Prevention Task Force, I’ll continue to fight towards a world without gun violence.
Honored to join the Dorrance family and @giffords.org in Napa for the Wine Country Unites kickoff, honoring 9-year-old Evelyn Dieckhaus, the Dorrances’ niece, who was tragically killed in the Covenant School shooting.
We won’t be intimidated — and we won’t allow the President to misuse our military to police our communities. The law is clear: the Insurrection Act doesn’t give him that power. I led fellow Democratic colleagues in warning this president to stand down and respect the Constitution.
Millions of families shouldn’t go hungry because of a government shutdown. I joined 212 of my Democratic colleagues in urging USDA to use every tool available to fund SNAP so 42 million Americans — including 35,505 households in our district — can continue putting food on the table.
People in our community aren’t asking for a handout — they’re asking for fairness and stability in their health care. Everyone deserves access to quality, affordable healthcare, and that’s what I’m fighting for.
Two years ago today, 18 lives were tragically taken in the mass shooting in Lewiston, Maine. We remember those we lost and stand with the survivors, families, and community still healing from this unimaginable tragedy. May we honor them with action to end gun violence.
Thank you to Caltrans and the Sonoma Valley Transportation Authority for delivering this much-needed improvement for Sonoma County. I'm glad I could chat with Supervisor Rebecca Hermosillo about how we helped in this great federal, state, and local partnership.
There’s never been a transportation problem that called out louder for a round about solution than this one. Roundabouts are safe, better for our environment and save taxpayers money.
There's a process for remodeling the White House and it should be followed. President Trump’s decision to completely demolish the East Wing of the White House to build a ballroom shows a total disregard for our history, our institutions, and the people’s house. www.nbcnews.com/politics/whi...
Rising health care premiums will hit independent contractors and small business owners especially hard. Congressional Republicans are driving up costs and undermining Americans’ ability to stay insured and save for their future.
In the event of an encounter with immigration agents in our community, make sure you and your family know your rights. For help with immigration casework call one of my offices: Napa Office: (707) 226-9898 Santa Rosa Office: (707) 542-7182 Woodland Office: (530) 753-5301
IF APPROACHED BY ICE AGENTS OR POLICE
You do not have to reveal your immigration status and have the right to remain silent.

IF ICE AGENTS COME TO YOUR HOME
You do not have to open the door.
Ask to see a search warrant through the window or for it to be slipped under the door. It must be signed by a judge and have your name on it. 
A deportation warrant is not the same as a search warrant and does not authorize ICE agents to enter your home without permission. 
You have the right to refuse ICE permission to enter your home if agents do not present a valid warrant.
If ICE agents enter without a valid warrant, ask for the agents’ names and badge numbers.

IF YOU ARE ARRESTED OR DETAINED
You have the right to speak to a lawyer immediately.
You or your family can call your congressmember to help connect you to legal services.
You have the right to remain silent and refuse to sign any documents without advice from an attorney.
SI ERES ABORDADO POR AGENTES DE ICE O POLICIA
No tiene que revelar su estatus migratorio y tiene derecho a permanecer en silencio.
SI AGENTES DE ICE VIENEN A SU CASA
No tiene que abrir la puerta. 
Pide ver una orden de registro a traves de la ventana o que la pasen por debajo de la puerta. Debe estar firmada por un juez y tener su nombre. 
Una orden de deportacion no es lo mismo que una orden de registro y no autoriza a los agentes de ICE entrar a su casa sin permiso. 
Tiene derecho a negarle a ICE el permiso de entrar a su casa si los agentes no presentan una orden valida. 
Si los agentes de ICE entran sin una orden valida, pide los nombres y numeros de placa de los agentes. 
SI LE DETIENEN
Tiene un derecho a hablar con un abogado de inmediato. 
Su o su familia pueden llamar a su miembro del Congreso para ayudar a conectarse con servicios legales. 
Tiene derecho a permanecer en silencio y negarse a firmar cualquier documento sin el consejo de un abogado.
His reckless trade policies killed U.S. export opportunities and hurt consumers. Our farmers deserve a leader who fights for them, not one who sides with foreign producers over American agriculture.
We’re now entering the fourth week of a government shutdown, and it’s been more than a month since the House last held a vote. Americans are facing higher healthcare premiums and grocery prices, and Speaker Johnson still has Congressional Republicans on vacation.
How can it be that under this administration in just 9 months our national debt jumped to $38 trillion? I thought for sure we'd see savings from dropping all those 300 year old people from government programs. apnews.com/article/trum...
Wildfires wreak havoc on our communities. Even after the fires are out, the lingering smoke can harm our health and damage our farms, ranches, and crops. That’s why I introduced legislation to tackle these health risks head-on and provide federal support for states working to improve air quality.
