Who was ordered to take a leave of absence?

CBS "60 Minutes" correspondent Lara Logan and her producer have been ordered by the network to take a leave of absence. That’s on the heels of the investigation into the October story on the attack on a U.S. diplomatic facility in Benghazi, Libya. Internal review of the coverage is critical of network’s handling of the October story on the raid. Show during its coverage of the story relied on an interview with the security contractor, who claimed that he was at a U.S. mission the night in Libya, and it was an attack, but whose story later came into question. CBS Chairman Jeff Fager, also the executive producer of "60 Minutes" ordered Logan to take the leave of absence.
