The family of former Rep. Eddie Bernice Johnson (D-TX) announced that the retired lawmaker died on Sunday.

Johnson’s son, Kirk Johnson, shared the sad news on Facebook.

“I am heartbroken to share the news that my mother, Eddie Bernice Johnson, has passed away. She was a remarkable and loving mother, mother-in-law, grandmother and great-grandmother as well as a trailblazer and public servant,” Johnson’s son wrote in a Facebook post. “While we mourn the loss of an extraordinary woman, we celebrate her life and legacy. She will be deeply missed. Funeral services are pending.”

Johnson’s 30-year political career was marked by a history of many firsts including, becoming the first registered nurse elected to the House in 1992. She is also the first African American to represent North Texas and the first person of color to chair the House Committee on Science, Space, and Technology. Johnson was also the first Black woman elected to any seat in Dallas.

The former lawmaker was the third Texas woman — behind Lera Thomas and Barbara Jordan, both from Houston — to represent the state in the U.S. House. Johnson served as the chairwoman of the Congressional Black Caucus from 2001 to 2003.

Johnson’s career was not without controversies as the former lawmaker came under heavy criticism over a scholarship fund. In 201, the former lawmaker was accused of directing the funds toward relatives and the children of aides from the Congressional Black Caucus Foundation.

Johnson was the dean of the Texas Congressional Delegation before she retired from office in 2022.

Dallas Mayor Eric Johnson reacted to news of Johnson’s death, noting that the former lawmaker was a groundbreaking leader.

“I am stunned and saddened to learn of the passing of my dear friend, Congresswoman Eddie Bernice Johnson,” Dallas Mayor Eric Johnson wrote on X Sunday morning. “Congresswoman Johnson was a groundbreaking leader for this country and for our state and city, and there really are no words to express my profound sense of grief and loss at the passing of this legendary American.”
