David Letterman has become the target of death threats from a frequent contributor of a jihadist website, reports the Associated Press. The contributor asked the followers of the site if there was anyone who would "cut the tongue of this lowly Jew and shut it forever."
Letterman, who the wire service notes is not Jewish, was targeted by the forum contributor after joking about a drone strike by the U.S. military in Pakistan that killed al-Qaida leader Ilyas Kashmiri on June 5.
The Site Monitoring Service, a private intelligence organization that watches online activity, said on Wednesday the threat was posted a day earlier on the Shumukh Al-Islam forum, which the wire service notes is a popular Internet destination for radical Muslims.
The contributor identified himself on the site as as Umar al-Basrawi. He wrote that Letterman had made reference to both Osama bin Laden and Kashmiri and said that Letterman had "put his hand on his neck and demonstrated the way of slaughter."
The Site Monitoring Service, part of the Site Intelligence Group, provides information to government and commercial clients on what jihadists are saying on the Internet and traditional media.
The FBI is looking into the threat, Jim Margolin, spokesman for the bureau's New York office, told the wire service. "We take every potential threat seriously," he said.
CBS and Letterman's spokesman would not comment on the threat. CBS would not make available a transcript of Letterman's monologue on the killing of Kashmiri.
This is not the first time the late-night host has been the target of criminal threats. In 2009, a former CBS News producer tried to extort $2 million from Letterman by threatening to expose his affairs with members of his staff, the man was later jailed. A former painter at Letterman's ranch in Montana was jailed following a 2005 plot to kidnap the TV hosts nanny and son.
Letterman's show, which films in New York City, is currently on a summer hiatus
