Rep. John Campbell (R-Calif.) will not run for reelection in 2014, he announced Thursday. He will retire at the end of the 113th Congress.

"At the end of this term, I will have spent 14 years serving in full-time, elected politics," Campbell said in a statement. "I am not, nor did I ever intend to be, a career politician. I am ready to begin a new chapter in my life."

Campbell first announced his decision on the Hugh Hewitt radio show. He represents a Republican-leaning Orange County district that gave Mitt Romney nearly 55 percent of the vote in 2012.

Campbell is the 15th member of the House to either resign, run for higher office or announce plans to retire so far this cycle.

In his statement, Campbell promised not to stop fighting for conservative causes, even though he is leaving office.

"My passion for the conservative issues for which I have fought so vocally over that span has 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 said.
