CHICAGO -- The Elvis impersonator at a Chicago block party may have looked familiar to some of the guests -- he used to be their governor.
Former Illinois Gov. Rod Blagojevich demonstrated his love for Elvis Presley with a short surprise performance at a downtown Chicago block party Friday, singing "Treat Me Nice" to several hundred people.
Blagojevich was paid for the performance thrown by a Chicago sound production studio but publicist Glenn Selig declined to say how much.
But he says some of the money is going to a charity supporting cancer patients.
Blagojevich, a longtime Elvis fan, often makes references to the entertainer during public appearances.
Blagojevich faces federal charges alleging he tried to sell or trade President Barack Obama's vacant U.S. Senate seat.
He denies wrongdoing.
