The U.S. Navy confirmed this week that it has launched an investigation into whether the former SEAL who killed Usama bin Laden revealed classified 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," an NCIS spokesman said.

"In response, NCIS has initiated an investigation to determine the merit of the allegations."

O'Neill, 38, a member of SEAL Team 6, was part of the operation in 2011 that killed bin Laden at a compound in Abbottabad, Pakistan.

He recounted the dramatic cross-border raid as part of a Fox News special that aired in November. 

Kelly Wright sat down this morning with former Navy SEAL Carl Higbie, who wrote the book "Battle on the Homefront."

Higbie also faced issues about what he could and could not reveal in his book.

Higbie believes the Obama administration and the Pentagon don't want any information going out that they don't control. 

"This is characteristic of the Obama administration and the D.O.D. They want to be the ones to control the flow of information. If they have somebody telling a different story or something that doesn't highlight the president in a positive light, they want to be able to squash it as soon as they can," said Higbie. 

He said he spent two years trying to get his book vetted by the Pentagon, but met continual "bureaucratic red tape" and eventually published it anyway.

Higbie pointed out that no one is investigating the "unprecedented access" given to Hollywood for the 2012 movie "Zero Dark Thirty."

"If they're going to investigate him for revealing classified information, they really need to look at the president and say, 'hey, you gave Hollywood unprecedented access to some of the same things for the movie that they put out just to paint himself in a positive light. So they really need to forward the investigation onto him as well."
