John Brennan, President Obama’s nominee to run the Central Intelligence Agency, is getting renewed scrutiny for a highly questionable claim he made during his confirmation hearings last week. On Tuesday, two Republicans on the Senate Select Committee on Intelligence, Marco Rubio and James Risch, wrote to Brennan to request additional information concerning Ali Harzi, a suspect in the attacks on U.S. facilities in Benghazi.

Brenan, in an exchange with Rubio, had said of Harzi that the U.S. government “didn’t have anything on him.” The claim is almost certainly false. The U.S. government provided evidence of Harzi’s involvement in those attacks to the governments of Turkey and Tunisia, which had both held Harzi as the U.S. tried to gain access to him for questioning.
