Washington, D.C. ? The White House has offered to let congressional investigators interview three former officials in an inquiry into what the administration knew about the friendly-fire death of Army Ranger Pat Tillman.

The aides are Dan Bartlett, former White House counselor; Scott McClellan, former press secretary; and Michael Gerson, former speechwriter. The House Oversight and Government Reform Committee agreed to White House demands that initial interviews be conducted without a transcript and with White House attorneys present.

If investigators determine the aides have relevant information, they would be asked to return for transcribed interviews. The White House has reserved the right to oppose that by claiming executive privilege, according to a letter Thursday from the committee’s chairman and top Republican to White House counsel Fred Fielding.
