Lindsey Graham Threatens All Obama Nominations Over Benghazi Witnesses

Wants more information on survivors

Sen. Lindsey Graham, R-S.C., says he'll block a vote on President Obama's nominees until the White House provides more information about the survivors of last year's deadly attack on the U.S. consulate in Libya.

Graham, a vocal critic of what happened at Benghazi, posted on Twitter that he'll block "every appointment" from getting a vote in the U.S. Senate.
