Rep. John Kline announced he will not seek another term in Congress.
The Republican from Minnesota's Second Congressional District in the St. Paul suburbs said in a statement that after "much thought and deliberation" he had decided not to run.
First elected in 2002, Kline has become an influential chairman of the House Education and Workforce Committee, where he has sought to reshape federal education and training policy, including an overhaul of the No Child Left Behind law.
Kline served as military aide to Presidents Carter and Reagan but referenced Reagan in his statement:"His vision of America as a ‘shining city on the hill’ has guided my decisions throughout my tenure in Congress."
He will have served seven terms when he leaves Congress next year.
The district is changing and may be trending to the DFL, as President Obama won a majority of votes in 2012. The DFL have two candidates considered serious, and several could emerge on the GOP side.
Given a shrinking number of competitive House seats, the Second Congressional will be sharply contested and likely see millions in outside spending in the 2016 race.
