Republican Congressman Doug LaMalfa of Northern California has passed away at the age of 65. LaMalfa, who served as a representative for California’s 1st District, was remembered fondly by his colleagues and constituents.

Tom Emmer, the GOP Majority Whip, shared the news of LaMalfa’s death on social media, describing him as “a devoted father and husband” and recognizing his dedication to serving both his constituents and rural America.

LaMalfa’s district, which he represented, stretches from Siskiyou County near the Oregon border and includes the rural areas of Shasta and Sutter Counties. His commitment to these communities was a hallmark of his political career.

As news of his passing spread, tributes poured in from politicians across the political spectrum. His death marks a notable change in the composition of the House, as the Republican majority narrows.

The Butte County Sheriff’s Office reported receiving a call regarding a “medical emergency” at LaMalfa’s residence on Monday evening, which led to the discovery of his passing.

The 65-year-old was taken to a hospital for emergency surgery, which is when he passed away.

A cause of death is under investigation.

President Trump remembered LaMalfa during a speech on Tuesday.

“He was the leader of the Western Caucus, a fierce champion on California water issues,” Trump said. “He was clear on what he wanted, ‘release the water,’ he’d scream out, and a true defender of American children. He was a defender of everybody.”

Governor Gavin Newsom remembered LaMalfa in a post on X, also saying that flags at the State Capitol will be at half-staff.

“Congressman Doug LaMalfa was a devoted public servant who deeply loved his country, his state, and the communities he represented,” Newsom said. “While we often approached issues from different perspectives, he fought every day for the people of California with conviction and care. He will be deeply missed.”

With Lamalfa’s passing, the GOP’s majority in the House now stands at 218 Republicans to 213 Democrats. His district was drastically redrawn by Proposition 50, which voters approved in November.

LaMalfa’s office released this statement on his passing:

Early this morning Congressman Doug LaMalfa returned home to the Lord. He leaves a lasting legacy of servant leadership kindness to the North State. His humor and work effort are legendary – with one reporter once saying he’d look in the back yard of every BBQ just to see if Doug was there visiting.

Congressman LaMalfa cared deeply for the people he served and worked tirelessly to hold the government to its word to fix our failing forests, build water storage, and leave people to be free to choose what is best for themselves. His tragic and unexpected passing leaves a deep impact on many. He leaves behind his amazing wife Jill, four children, one grandchild, two sisters and a host of cousins.
