Kathryn Bigelow Osama Bin Laden film faces US probe
US officials are investigating if potentially classified information about the killing of Osama Bin Laden was given to a film-maker.
Representative Peter King, a New York Republican, said he was "pleased" that the Pentagon and the CIA had responded to a request he made in August.
Mr King is concerned leaks would put the famed Seal Team 6 "in danger".
Director Kathryn Bigelow and Sony Pictures expect a film about the raid to be released in October 2012.
In his August letter to the inspectors general of the CIA and the Department of Defense, Mr King cited a column in the New York Times where contributor Maureen Dowd wrote that administration officials gave Ms Bigelow "high-level access" to the mission.
The White House called that report - and Mr King's claims - "ridiculous".
Mr King is the chairman of the House Committee on Homeland Security, has previously called for investigations into possible phone hacking of 9/11 victims and whether al-Qaeda is actively recruiting US Muslims.
Ms Bigelow won a best director Academy Award for The Hurt Locker, a 2008 movie about a US army bomb disposal team set during the Iraq War.
