Sen. Richard Durbin says he's spoken with an Illinois prosecutor and the Senate ethics committee about embattled Sen. Roland Burris.

The Senate's No. 2 Democrat, Durbin said on Wednesday that he met with the Senate committee at its request. He said he won't comment about Burris, his Illinois colleague and fellow Democrat.

Durbin also said he met with Sangamon County State's Attorney John Schmidt last week. He says Schmidt is reviewing Burris' testimony before the Illinois House impeachment panel to determine if criminal charges are warranted.

Burris has been under scrutiny after new revelations about how he was appointed to Obama's former seat by Rod Blagojevich when he was the state's governor.
