“60 Minutes” correspondent Lara Logan and her producer Max McClellan are taking a leave of absence after an internal review at CBS News acknowledged major problems with a segment broadcast last month. Logan highlighted an alleged eyewitness’s sensational account about the 2012 terrorist attacks on the U.S. compound at Benghazi, Libya. But much of that security contractor’s story appears to have been fabricated, leading to his publisher taking the extraordinary step of pulling his book about Benghazi.

Here’s a timeline of the “Benghazi Trainwreck”, and here are seven major problems with the story Logan aired.

Among the unanswered questions surrounding this black eye for the flagship CBS news program: “why the hell did CBS News continue to defend this story after evidence emerged that Davies had fabricated his tale?” Jay Rosen chronicled the network’s “reckless denials” here.

Also, did Logan’s husband play a role in getting some unsourced allegations on the air in her Benghazi piece? Perhaps most important, why hasn’t Logan been fired, rather than merely asked or forced to take a leave of absence? After an inaccurate “60 Minutes” story aired in 2004 about George W. Bush’s National Guard service, CBS commissioned an independent panel (rather than an internal review) and eventually fired several employees who were involved in producing the segment.

Any relevant comments are welcome in this thread.
