A day after his public swearing-in, Obama is celebrating at a staff ball Tuesday night intended to thank campaign, White House and inaugural staffers for their efforts.Pop diva Lady Gaga, who campaigned for Obama, will perform.
The staff ball is a private affair. On Monday, tens of thousands attending the two official inaugural balls watched the president and first lady share a dance as Jennifer Hudson crooned "Let's Stay Together."
Staffers paid $10 per ticket to attend the staff ball. Proceeds will support a memorial fund for Alex Okrent, a campaign worker who collapsed and died at Obama's campaign headquarters in July.
