NEW YORK (AP) – NBC News has assigned the head of its own investigative unit to look into statements made by anchor Brian Williams about his reporting in Iraq a dozen years ago.

A source at the network who requested anonymity because the person is not authorized to speak on personnel matters confirmed the investigation on Friday. Williams has apologized for falsely saying on the air that he was in a helicopter hit by a rocket-propelled grenade while in Iraq in 2003.

Richard Esposito, a former editor at the New York Daily News now at NBC, will head the investigation. The incident has ballooned into a full-blown crisis for NBC and Williams, whose ‘‘Nightly News” is the top-rated evening news program.

There was no word on whether Williams will be on the broadcast Friday.
