Sen. Lindsey Graham is determined to get more answers about the deadly Sept. 11 attack against the U.S. consulate in Benghazi, Libya.
Now the South Carolina Republican says he will hold up Senate confirmation of President Barack Obama's nominees to head the Pentagon and the CIA until he gets that information.
Graham accuses the White House of "stonewalling" requests to release more information about the attack that killed four Americans, including the U.S. ambassador to Libya. He said Sunday on CBS' "Face the Nation" that "We're going to get to the bottom of Benghazi."
The White House has urged quick approval of former Sen. Chuck Hagel as defense secretary and John Brennan, Obama's top counterterrorism adviser, as CIA director.
