Ways & Means Republicans are attempting to block our efforts to investigate DOGE’s access to sensitive taxpayer data. Your personal data isn’t Musk’s playground. It’s time the Republican Party which is the majority party stand up to him and protect American taxpayers.

GOP lawmakers brush back inquiries on DOGE access to Treasury, SSA systems

House Ways and Means Republicans shot down a pair of resolutions from Democrats seeking information on the Elon Musk-led group’s IT intrusions.

Is Social Security a ‘Ponzi Scheme’?

To all retired Americans, its benefits are very real.

Rep. Mike Thompson@mikethompson.house.govMar 14(source)

FACT: Social Security is an earned benefit that allows over 153,000 residents in our district to retire and live with dignity and puts $3.4 billion into our local economy each year. Previous attempts to cut or privatize Social Security were wildly unpopular, and for good reason.

Rep. Mike Thompson@mikethompson.house.govMar 14(source)

#FactCheckFriday Elon Musk, the richest man in the world, claims your hard-earned Social Security benefits are a “Ponzi scheme.”

Congressional Republicans' partisan funding bill slashes critical services and hands this destructive administration a blank check. Read my full statement below.

"Congress’ job isn’t to write a blank check to the President. Our job is to pass a bill that directs the President to fund the services and priorities that matter most to the American people.

“Congressional Republicans’ partisan funding bill is dangerous. That’s why House Democrats stood united and voted “No” to protect the Social Security, Medicare and Medicaid, and veterans benefits millions of Americans rely on every day. And I thank our California Senators, Alex Padilla and Adam Schiff, and the other senators who stood with us and opposed this bill as well.

"It’s unthinkable that our party’s leadership in the Senate folded to the President and greenlit this bill that slashes critical services and hands this destructive administration a blank check. Make no mistake, the American people will pay the price.”

Deeply saddened by the passing of my colleague, Congressman Raúl Grijalva. Raúl was a fierce champion for protecting our climate and our lands, and he will be dearly missed. My prayers are with his loved ones. www.npr.org/2025/03/13/g...

Today’s ruling to reinstate tens of thousands of essential public servants is a big win in our fight against the President’s unlawful actions. Read my full statement below.

“A ‘sham’ is right. For months, President Trump and Elon Musk have unlawfully fired scores of federal workers who serve our veterans, support our farmers, ensure our national security, and more. Today’s ruling to reinstate tens of thousands of these essential public servants is a big win in our fight against the President’s unlawful actions.

“No person is above the law, which is why I’ve been working with my colleagues daily to fight the Administration in Congress, in the courts, and in the court of public opinion. Our efforts are working. I urge every American to keep holding the President and Musk’s feet to the fire.”

Great to join the League of American Bicyclists for their annual Bike Summit in Washington. Over the last twenty years, bike commuting has grown 60 percent nationwide. As Co-Chair of the Congressional Bike Caucus, I’m working to continue to make biking safer and more accessible.

The American people did not vote to gut Medicare and Medicaid, slash Social Security, and rip benefits away from veterans. Ways and Means Democrats have filed a resolution to demand answers from the Administration and it’s time our Republican colleagues join us.

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

Republican cuts to Medicaid threaten care for all of us. These cuts will force hospitals to cut services or shutdown altogether, limiting care for everyone in our community. In our district, 241,000 patients and $2 billion in economic impact are at risk. www.youtube.com/watch?v=ev5D...

Winters residents: My team is hosting in-person office hours today, March 12th, from 11am to 1pm. Please drop in to discuss with my team any support you may need and stay tuned for more sessions throughout our district.

Read my full statement on the passage of the Republican funding bill below.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

I’m for Social Security, Medicare and Medicaid, and veterans. I voted “No” on the Republicans’ partisan funding bill.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

That’s why the Republicans' latest funding resolution is so dangerous. Republicans are trying to pass a blank check for the President and Elon Musk, freeing them from any legal obligation to protect Social Security, Medicare and Medicaid, and veterans’ benefits.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

Congress’ job isn’t to write a blank check to the President. Our job is to pass a bill that directs the President to fund the programs and priorities that matter most to the American people.
