Rep. John Barrow (D-Ga.) will not run for the Senate in 2014, he announced Tuesday, ending months of speculation over whether the conservative Democrat would make a bid.

"I'm grateful for the encouragement I've received from folks all across the State of Georgia, but I've decided that I will not be a candidate for the Senate in 2014," Barrow said in a statement. "I enjoy my work on behalf of the folks in the 12th District, and I look forward to continuing to serve them in the House of Representatives."
