WASHINGTON (CBSMiami) – The United States may continue to be without a director of the Central Intelligence Agency and the Defense Department if U.S. Senator Lindsey Graham gets his way.

Sunday on “Face the Nation,” Senator Graham vowed to block the confirmation votes for CIA director John Brennan and Defense secretary nominee Chuck Hagel until he get whatever information he is searching for on the Benghazi, Libya attack last September.

The Benghazi attacks have been the subject of right-wing anger for months, but the details have largely been settled by constant Congressional hearings, including one from then-Secretary of State Hillary Clinton.

Still, Graham plans to hold up the nominations until he gets more information from the White House. It’s unknown exactly what Graham’s fishing expedition is looking for, but Graham told “Face the Nation” Sunday, “This was incredibly mismanaged. And what we know now, it seems to be a very disengaged president.”

Hagel’s approval as defense secretary has been in question due to Republican objections, even though Hagels is a former Senate Republican himself. Both Brennan and Hagel went through tough confirmation hearings in the past few weeks.

Historically speaking, only a few presidential nominees to cabinet positions have been rejected by the Senate. The most recent was to John Powers during the administration of George H.W. Bush in 1989.
