Lindsey Graham Calls For Extrajudicial Killing Of American Al Qaeda Operative Adam Gadahn

Sen. Lindsey Graham (R-S.C.) took to Twitter on Monday to urge the U.S. to use lethal force against American-born al-Qaeda operative Adam Gadahn.

In multiple tweets, Graham described how he felt the American government should handle Gadahn, who has called for more attacks on the U.S. in a recent video produced by an al-Qaeda foundation.

Graham also wrote that Gadahn could appropriately be killed without trial -- an extrajudicial act that would be legal according to a Justice Department explanation earlier this year.

In his video, Gadahn had praised the Sept. 11, 2012, destruction of the U.S. mission in Benghazi, Libya, and encouraged similar attacks, offering a bounty for the killing of U.S. Ambassador to Yemen Gerald Feierstein, according to CNN.

"The dead American ambassador Christopher Stevens wasn't a friend of Libya," Gadahn said in the video.

Graham, a harsh critic of the way the Obama administration handled the aftermath of the Benghazi attack, also pushed out a tweet calling that response "unacceptable."
