The contributor, who identified himself as Umar al-Basrawi, was reacting to what he said Letterman did after the US military announced on June 5 that a drone strike in Pakistan had killed al-Qaeda leader Ilyas Kashmiri.

Al-Basrawi 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.”

“Is there not among you a Sayyid Nosair al-Mairi … to cut the tongue of this lowly Jew and shut it forever?” Al-Basrawi wrote, referring to El Sayyid Nosair, who was convicted of the 1990 killing of Jewish Defense League founder Meir Kahane. Letterman is not Jewish.
