McClatchy:

When “60 Minutes,” perhaps the United States’ premier news program, apologized for featuring a security contractor in its report on Benghazi whose story turned out to be a lie, it said had been “misled.” But a close examination of the controversial piece by McClatchy shows that there are other problems with the report, which renewed debate about one of the most contentious events in recent U.S. diplomatic history.
In its first acknowledgement that the issues with the report may go deeper than just the interview with security supervisor Dylan Davies, CBS on Wednesday, in response to a series of questions posed by McClatchy, said that it had begun “a journalistic review that is ongoing.”
“60 Minutes” spokesman Kevin Tedesco said the review had begun as soon as questions were raised about the piece, but he declined to elaborate in an email exchange and did not respond to the specific issues McClatchy raised.
