(CNN) - Republican Rep. John Campbell of California announced Thursday he will not seek re-election next year in the state's 45th Congressional District.
The five-term congressman, who served in the California state legislature before coming to Capitol Hill, said it was time to start a "new chapter."
"At the end of this term, I will have spent 14 years serving in full-time, elected politics. I am not nor did I ever intend to be a career politician," he said in a statement. "I am ready to begin a new chapter in my life."
Campbell, whose family has strong ties to Southern California, ran for Congress in a 2005 special election to fill the seat vacated by then-Rep. Christopher Cox, who was tapped by President George W. Bush to head the Securities and Exchange Commission.
Previously, Campbell served in the state assembly for four years and the state senate for one year.
In his statement, he said his conservative values have "not waned."
"But in the future, I will continue the fight for more freedom and a less authoritarian government as a private citizen rather than elected official," he added.
His statement ended with a line he has often used: "Drive fast and live free."
With a mostly conservative record in the House, he easily won re-election last year with 58% of the vote.
