Johnson’s family announced his death in a Facebook post, which read: “It is with a heavy heart that the family of Congressman Sam Johnson announces his passing earlier today in Plano, Texas.

“Sam Johnson was a devoted husband, father, grandfather, great grandfather, and friend, as well as a mentor, patriot, and American hero whose sacrifices will never be forgotten. He is now with his beloved wife, Shirley, and their son, Bob. Together they are reunited in their eternal home with Jesus Christ.”

The post did not give further details about his death.

Elected to the House of Representatives in 1991, Johnson became a prominent conservative figure during his time in Congress. He departed in 2019, at which point he was the chamber’s oldest member.

Prior to his time as a lawmaker, Johnson was in the Air Force, serving as a fighter pilot during his 29-year stint, which saw him fly in more than 60 combat missions.

In 1966, his plane was shot down over North Vietnam and he was captured as a prisoner of war. He was kept captive for seven years.

Senator Ted Cruz (R-TX) said Johnson was “the definition of a patriot and a public servant.”

“He proudly defended our freedoms, both on the battlefield and in the hallways of the House, and I was honored to serve alongside him in the #TX congressional delegation,” he wrote on Twitter.

House Minority Leader Kevin McCarthy (R-CA) spoke of his admiration for Johnson, adding that he would miss him.

“No one embodied service and love of country like Rep. Sam Johnson,” he wrote.

Steve Scalise, House Minority Whip, (R-LA) said: “America lost one of its best today. Sam Johnson was my personal hero. His courage, integrity, grit as a POW for 7 years at the Hanoi Hilton, and dedication to our country inspired us all.

“It was an honor to serve alongside him in Congress.”

Sen Marsha Blackburn (R-TN) said she was blessed to “serve with such a kind, courteous and brave soul.”

She wrote: “Sam Johnson exhibited valor and love of country as a citizen, a soldier, a POW and US congressman. He was truly exceptional in every way.”

Ways and Means Committee Chairman Richard E. Neal (D-MA) said he had been grateful for the opportunity to work with him

In a statement, he said: “Sam Johnson was a true patriot who devoted his life to service of the nation he loved. His heroics in battle earned him the respect of Americans across the country, and he represented the people of Texas with honor in Washington, D.C.

“Members on both sides of the aisle valued his kindness and good humor and will surely miss him greatly. My prayers are with his family and loved ones during this difficult time.”

Johnson is survived by two daughters and 10 grandchildren.
