Lara Logan apologizes for '60 Minutes' Benghazi report NEW: Publication of book containing account is suspended Reporter: CBS was "wrong" in report that raised questions about Benghazi attack Official claims discrepancies between CBS source's accounts and what he told FBI (CNN) -- CBS correspondent Lara Logan apologized Friday and said the network was "wrong" for a "60 Minutes" report that raised questions about the Obama administration's response to last year's attack on the U.S. diplomatic compound in Benghazi, Libya. The assault left four Americans dead, including Ambassador Christopher Stevens. In this case, we were wrong. We made a mistake," Logan said on "CBS This Morning." That's disappointing for any journalist. It's very disappointing for me. A primary source for the "60 Minutes" report on October 27 was a security contractor using the pseudonym "Morgan Jones," later identified as Dylan Davies. Davies told CBS he was able to reach the Benghazi compound on the night of September 11, 2012, scale a wall and even fight off a militant. Also on Friday, the publisher of a book containing Davies' account said it was suspending the sale and publication of the book. Threshold Editions, an imprint of Simon & Schuster, is recommending that booksellers not sell "The Embassy House" and return the books, spokeswoman Jennifer Robinson told CNN. The "60 Minutes" story broadcast October 27 cast doubt on whether the Obama administration sent all possible help to try to save Stevens and his three colleagues. The story was then cited by congressional Republicans who have demanded to know why a military rescue was not attempted. Benghazi attack timeline On Friday, Logan responded to questions from CBS's Norah O'Donnell, who pressed her for details about Davies. "What we know now is, he told the FBI a different story to what he told us," Logan said. That was the moment for us when we realized that we no longer had confidence in our source and we were wrong to put him on air, and we apologize to our viewers. Logan was also asked about how CBS vetted Davies and his story. "We verified him, confirmed who he was, that he was working for the State Department at the time, that he was in Benghazi at the special mission compound the night of the attack," Logan said. He showed us -- he gave us access to communications he had with U.S. government officials. "The Embassy House" tells the same story Davies told Logan. Davies also told Logan that he acted in violation of his employer's orders to stay away from the compound. Since the revelations about problems with the story, Logan said CBS has tried to contact Davies but has not heard from him. Congressman: Benghazi questions need answers The news show apology comes a day after CBS issued a statement saying, "60 Minutes has learned of new information that undercuts the account told to us by Morgan Jones of his actions on the night of the attack on the Benghazi compound. On Thursday a U.S. official told CNN that there were discrepancies between the contractor's accounts to the FBI and CBS, although the official did not specify them. A second U.S. official told CNN the same thing Friday. When Logan was asked Friday why CBS was willing to stand by its report after Davies lied to his employer, she said, "because he was very upfront about it; that was part of his story." The incident report also revealed the real name of "Morgan Jones" to be Davies. Davies' co-author, Damien Lewis, also told CNN this week that Jones never wavered in his story. "He's been consistent in the story from the word go," Lewis said. Not only that, he's the kind of guy who downplays his role. Reached Friday after CBS's apology, Lewis said he would have nothing more to say until Davies comments. Hearing set for next week With the help of a rescue team that arrived from Tripoli at 1:15 a.m., the agents rescued about 30 Americans and took them to the CIA annex. They also took Stephens and Smith, although their conditions at that time have not been made clear. CNN's Jim Sciutto, Evan Perez and Elise Labott contributed to this report.
