The AP reports that Texas Democrat Jack Brooks, who would have turned 90 on Dec. 18, has died.

Jack Brooks, who spent 42 years in Congress representing his Southeast Texas district and was in the Dallas motorcade in 1963 when President John F. Kennedy was assassinated, has died. He was 89.

Brooks was among the last links to an era when Democrats dominated Texas politics and was the last of “Mr. Sam’s Boys,” protégés of fellow Texan and legendary 21-year Democratic House Speaker Sam Rayburn in the state’s congressional delegation.
