Senate Democratic leaders say they'll reject any appointee named by Blagojevich but Burris said late Saturday he still planned to go to Washington on Monday to claim the Senate seat.
Burris said he would attend a Sunday evening prayer vigil at a Chicago church before addressing his supporters.
Although Burris had been scheduled for an interview on ABC's "This Week with George Stephanopoulos," the network said Sunday he would not appear as the program focused on the fighting in the Middle East.
