Good news! The Supreme Court (7 to 2 vote) agrees with the American people that untraceable Ghost Guns are, in fact, guns. This ruling makes it more difficult for bad people to get untraceable guns.

Supreme Court upholds Biden rule requiring serial numbers and background checks for ghost guns

The Administration’s leak of sensitive national security information is reckless — and the whole world is watching.

Rep. Mike Thompson@mikethompson.house.govMar 27(source)

Two years ago, a shooter senselessly killed 3 students and 3 staff at Covenant School in Nashville, Tennessee. Today, we remember those lost and recommit to passing sensible policies to keep our communities safe.

I’m calling on the President to initiate an independent investigation into the massive classified materials leak by the Secretary of Defense, the Director of National Intelligence, the CIA Director, the National Security Advisor, and the Vice President. Read my full letter below.

Rep. Mike Thompson@mikethompson.house.govMar 25(source)

The Administration's leak of sensitive national security information is reckless and those involved must be held accountable. Only by the grace of God, were no American servicemembers killed. My update below.

Rep. Mike Thompson@mikethompson.house.govMar 25(source)

Congressional Republicans must join Democrats in a swift and substantive investigation into this enormous national security breach.

Rep. Mike Thompson@mikethompson.house.govMar 25(source)

The Administration’s leak of sensitive national security information is reckless. It is deeply concerning that we can’t trust our senior-most officials in the White House to uphold the safety of our country. www.reuters.com/world/us/top...

Top Trump officials mistakenly divulged military plans to journalist

Top Trump administration officials, including U.S. Vice President JD Vance and Secretary of Defense Pete Hegseth, mistakenly included a journalist in a messaging group discussing strikes against Yemen's Iran-aligned Houthis, according to a firsthand account by The Atlantic magazine.

Six years ago today, March for Our Lives brought hundreds of thousands of people together to demand action to prevent gun violence. Their voices strengthened our movement.

For 15 years, the Affordable Care Act has saved Americans millions of dollars in medical bills. That’s why I’m working with my colleagues on the Ways & Means committee to ensure the ACA expanded tax credit is renewed so we can continue to keep costs down for Americans.

Grateful to the over 150 Lake County community members who joined me for "Coffee with Our Congressman." I’m committed to fighting Congressional Republicans’ plans to cut health care to fund tax cuts for the ultra-rich.

Rep. Mike Thompson@mikethompson.house.govMar 22(source)

Three years ago today, a gunman took ten innocent lives at a King Soopers in Boulder, Colorado, forever changing the community. Today, we remember the victims including Officer Eric Talley who gave his life to protect others. We must honor their memory with action.

Rep. Mike Thompson@mikethompson.house.govMar 21(source)

Firing tens of thousands of VA employees while we have more veterans than ever relying on VA care will increase wait times and leave our vets without the care they need when they need it. We need more doctors and nurses at the VA, not less. Read more for yourself. (3/3) apnews.com/article/vete...

Trump administration plans to cut 80,000 employees from Veterans Affairs, according to internal memo

The Department of Veterans Affairs is planning an “aggressive” reorganization that includes cutting 80,000 jobs from the sprawling agency.

Rep. Mike Thompson@mikethompson.house.govMar 21(source)

FACT: President Trump and Musk’s DOGE is firing 83,000 VA staffers. After our historic expansion of Veterans benefits in 2022 under the Biden Administration, 740,000 more veterans have signed up for care. (2/3)

Rep. Mike Thompson@mikethompson.house.govMar 21(source)

#FactCheckFriday When asked about his plans to fire Veterans Affairs employees, the President recently stated that: “We love our veterans. We’re gonna take good care of them.” (1/3)

Middletown residents: I will be hosting Coffee with the Congressman today, March 21st, from 11 am to 12 pm. Please drop in to discuss issues impacting you and our community.

Rep. Mike Thompson@mikethompson.house.govMar 21(source)

Thank you to North Bay Labor Council for supporting federal workers. DOGE is firing the federal workers who help us fight fires, deliver social security, help veterans, conduct ag research, repair our roads and bridges, ensure air travel is safe, staff IRS offices, and more. We won’t stand for it.

Rep. Mike Thompson@mikethompson.house.govMar 20(source)

Congressional Republicans are cutting Medicaid to fund tax cuts for the ultra-rich. This will reduce health care services at best, and shutter local hospitals at worst. This affects care for every single member of our community.

A tale of two events: GOP congressman deflects on Medicaid cuts, as Democrats pounce

While Democrats hold no power in Washington, they could win the public relations war on the budget by holding in-person events where Republicans wont.
