Robert O'Neill, who is allegedly the Navy SEAL who shot Osama Bin Laden dead, is under investigation by the U.S. Navy for revealing classified information.

The U.S. Navy has confirmed they are currently investigating O'Neill, according to the AFP. The former SEAL Team Six member is believed to have released confidential information concerning the 2011 raid that killed the 9/11 mastermind, though what information he leaked exactly has not been specified. It also remains unclear as to whom O'Neill released the information.

"The Naval Criminal Investigative Service (NCIS) is in receipt of an allegation that Mr O'Neill may have revealed classified information to persons not authorized to receive such information," U.S. spokesperson Ryan Perry told the AFP. "In response, NCIS has initiated an investigation to determine the merit of the allegations."

The Daily Beast first broke the story concerning the Navy's investigation and received the same statement from Ed Buice, an NCIS spokesperson.

O'Neill, 38, sparked controversy when he claimed to be the SEAL who fired the shot that killed Bin Laden; however, special operations sources contradict aspects of his story.

Another SEAL involved in the raid, Matt Bissonnette, also claims to have shot the terrorist. Bissonnette wrote the book "No Easy Day," recounting the events of the raid.

Although O'Neill has not written anything about the raid, he has given interviews concerning it, partaking in an Esquire profile and a Fox News documentary, both in which he was incognito. However, once he was identified, he continued speaking, being interviewed by the Washington Post.

O'Neill claims the information he made public did not breach any military non-disclosure agreement. The office of GOP Rep. Duncan Hunter, who knows O'Neill, told the Daily Beast the Navy had not produced evidence of O'Neill's wrongdoing.

"Regardless of whether you think Rob O'Neill should have identified himself or not, an investigation will need turn up credible evidence that disclosures were made-and on that front, at least so far, there's no compelling evidence that occurred," Joe Kasper, Hunter's chief of staff, said.

However, in the last month the United States Naval Special Warfare Command has criticized those who disclosed information and warned anyone planning to do so, reports the Christian Science Monitor.

"Violators of our Ethos are neither teammates in good standing, nor Teammates who represent Naval Special Warfare," Rear Adm. Brian Losey and Force Master Chief Michael Magaraci wrote in a letter. "We do not abide willful or selfish disregard for our core values in return for public notoriety and financial gain, which only diminishes otherwise honorable service, courage and sacrifice."
