Washington (CNN) - Saxby Chambliss, the Republican senator from Georgia, said Friday that the "legislative gridlock and partisan posturing" had grown so impenetrable in Washington that he would not seek re-election in 2014,

"This is about frustration, both at a lack of leadership from the White House and at the dearth of meaningful action from Congress, especially on issues that are the foundation of our nation's economic health," Chambliss wrote in a statement announcing his retirement. He pointed to partisan haggling over raising the debt ceiling in 2011, and more recently to the bickering that transpired over a deal to avoid the fiscal cliff.
