Sen. Lindsey Graham (R-S.C.) said Tuesday that Congress should appoint a joint select committee to investigate the government's handling of intelligence regarding the Boston Marathon bombing suspects.

"When it comes to Boston, we need a joint select committee to look at FBI, the CIA and Homeland Security," Graham told CNN on Tuesday. "The system did not work as designed."

Graham has been a vocal critic of the Obama administration in the aftermath of the bombing, suggesting that intelligence and law enforcement agencies did not properly coordinate a response after Russian intelligence tipped off American officials that bombing suspect Tamerlan Tsarnaev could have radical ties. Last week, Graham told CNN that the "ultimate blame, I think, is with the administration."
