CBS News correspondent Lara Logan and her producer Max McClellan are scheduled to return to 60 Minutes quite soon, after the pair took a public beating last year for airing the Benghazi lies of British military contractor Dylan Davies. But they’re not the only ones to blame.

Everyone wants to know: Why did CBS correspondent Lara Logan trust Dylan Davies, the now-discredited security contractor, and the story he told 60 Minutes about the 2012 attacks in Benghazi, Libya? It’s truly mystifying—unless, that is, you know about her last significant lapse in professional judgement involving a security contractor.

Last week CBS correspondent Lara Logan announced that 60 Minutes would apologize on Sunday night’s broadcast for airing an interview with a Welsh security contractor named Dylan Davies, who lied about visiting the American consulate in Benghazi, Libya, when it came under attack in September 2012. You can watch Logan’s tepid apology—in her words, a “correction”—in the video above.

Today CBS newsmagazine 60 Minutes retracted its bombshell report about security failures during the September 11, 2012 attacks in Benghazi, Libya. The embarrassing retraction, announced on CBS This Morning by Lara Logan, came nearly a week after The Washington Post challenged the veracity of one of 60 Minutes’ sources, a security contractor named Dylan Davies, and hours after the New York Times revealed that Davies supplied FBI investigators with a very different story.
