Trouble may be looming for President Barack Obama's pick for CIA director. Sen. Lindsey Graham, a member of the Armed Services Committee, says until the administration provides answers on the deadly Sept. 11 assault in Libya that killed the U.S. ambassador and three other Americans, he's going to delay the confirmation of John Brennan. Graham said the administration has been stone-walling on Benghazi and it has to stop. At issue is the finger-pointing about who changed the talking points concerning what happened in the attack.
