John Culberson was elected to the Texas House in 1986 and served there for seven consecutive terms. In his last term, his colleagues selected him to be House Republican Whip, responsible for solidifying party support in the state legislature.
Culberson emerged from a large field in the 2000 GOP primary for the District 7 seat in the U.S. House, then beat self-financed businessman Peter Wareing in a runoff with 58 percent of the vote.
Culberson went on to defeat Jeff Sell in the general election with 74 percent of the vote.
He was re-elected in 2002 with 89 percent of the vote.
