Obama: I'm ultimately responsible for diplomatic security in Benghazi

“What my attitude on this is is if we find out there was a big breakdown and somebody didn’t do their job, they’ll be held accountable,” said Obama in an interview with MSNBC’s Mika Brzezinski and Joe Scarborough, according to a report on that network’s website.

“Ultimately as Commander-in-Chief I am responsible and I don’t shy away from that responsibility,” Obama added.

The full interview, conducted after a rally in Nashua, N.H., is slated to air on Monday.
