A FORMER NAVY SEAL who shot Osama bin Laden and wrote a bestselling book about the raid is now the subject of a widening federal criminal investigation into whether he used his position as an elite commando for personal profit while on active duty, according to two people familiar with the case.

Matthew Bissonnette, the former SEAL and author of No Easy Day, a firsthand account of the 2011 bin Laden operation, had already been under investigation by both the Justice Department and the Navy for revealing classified information. The two people familiar with the probe said the current investigation, led by the Naval Criminal Investigative Service, expanded after Bissonnette agreed to hand over a hard drive containing an unauthorized photo of the al Qaeda leader’s corpse. The government has fought to keep pictures of bin Laden’s body from being made public for what it claims are national security reasons.

The retired SEAL voluntarily provided investigators with a copy of his hard drive as part of an agreement not to prosecute him for unlawfully possessing classified material, according to the two people familiar with the deal.

The two people who spoke about the case, and other former SEALs The Intercept interviewed about Bissonnette, asked that their names not be used because they were describing an ongoing investigation and classified matters.
