President-elect Barack Obama will attend the free, Sunday afternoon event, which will feature musical performances by Bono, Bruce Springsteen and many others.
"The president-elect has respect for the Rt. Rev. Robinson, who offered his advice and counsel over the past couple of years," an inaugural official told Politico. "It also has the benefit of further reinforcing our commitment to an open and inclusive inaugural."
An Obama source denied to Politico that Robinson was brought on to appease angry gay rights activists.
"Robinson was in the plans before the complaints about Rick Warren," the source said. "Many skeptics will read this as a direct reaction to the Warren criticism — but it's just not so."
