Obama will fill in for Ted Kennedy in giving Sunday's commencement address at Wesleyan University, his campaign says.
"Ted and I talked about me filling in for him at Wesleyan University earlier this week," Obama said in a statement. "Considering what he's done for me and for our country, there's nothing I wouldn't do for him. So I'm looking forward to standing in his place on Sunday even though I know I won't be able to fill his shoes."
