Washington ? Roland Burris took his place as Barack Obama’s successor in the Senate on Thursday, ending a standoff that embarrassed the president-elect and fellow Democrats who initially resisted the appointment by scandal-scarred Illinois Gov. Rod Blagojevich.

“I do,” Burris said with a grin as Vice President Dick Cheney administered the oath of office to the former Illinois attorney general who takes Obama’s place as the Senate’s only black member.

More than a week after his colleagues were sworn in, Burris was seated without objection or a roll call vote, even though Majority Leader Harry Reid had said senators would have their voices heard on whether to accept his appointment.
