President-elect Barack Obama and two of his top aides met last week with federal investigators building a corruption case against Illinois Gov. Rod Blagojevich, accused of trying to swap Obama's Senate seat for cash or a lucrative job.

The interviews with Obama, along with incoming chief of staff Rahm Emanuel and adviser Valerie Jarrett, were disclosed Tuesday in an internal report produced for Obama on contacts with Blagojevich. Obama delayed releasing his report until those interviews were completed with U.S. Attorney Patrick Fitzgerald's staff, incoming White House attorney Greg Craig said in the review he wrote for Obama.
