BEAUMONT, Texas—Friends and relatives of former U.S. Rep. Jack Brooks gathered Sunday at Lamar University to celebrate his life, including his 42 years in Congress.

The 89-year-old Democrat died Tuesday in Beaumont.

He was in the motorcade in 1963 in Dallas when President John F. Kennedy was assassinated and is known for being in the famous photo of Lyndon Johnson taking the oath of office aboard Air Force One.

Brooks also served on the House Judiciary Committee, where he strongly supported President Richard Nixon's impeachment and in 1974 drafted the articles of impeachment the panel adopted. He also helped write the historic federal Civil Rights Act of 1964 that banned racial segregation.

Brooks lost a bid for a 22nd consecutive congressional term in 1994.
