David Letterman Target of Threat on Jihadist Website Urging to "Cut Tongue" of Host

David Letterman is back in headlines, and this time his safety may be in jeopardy. The FBI is investigating a threat made against the late night talk show host, after a commenter on an online forum for radical Muslims posted a comment urging others to "cut the tongue" of the comedian because of a joke he made on Late Night about Osama Bin Laden.

The comment was written on Tuesday by a person identified as "Umar al-Basrawi," which is believed to be an alias.

The poster told users of the Shumuka al-Islam forum to punish the host for a joke about dead al Qaeda leaders Osama bin Laden and Ilyas Kashmiri which he made on his CBS show June 8, Radar Online reports.

Al-Basrawi wrote that Letterman had "put his hand on his neck and demonstrated the way of slaughter," then threatening, "Is there not among you a Sayyid Nosair al-Mairi ... to cut the tongue of this lowly Jew and shut it forever?"

Letterman is not Jewish, but Presbyterian. He has yet to comment on the threats.
