The Washington Post reported Thursday that secret budget files provided by Snowden show that a U.S. military lab in Afghanistan analyzed DNA from bin Laden's body and confirmed his identity shortly after he was killed. The test results were "a conclusive match," the Post said.
The Pentagon denied more than a year ago it had any records of these tests in a Freedom of Information Act request by the Associated Press.
Bin Laden was killed by a Navy SEAL team at his Pakistan hideout in May 2011.
