President Hosts White House Wedding Reception

The United States Marine Band played a selection of standards and other "oldies-but-goodies," one of the guests tells PEOPLE, for the Republican-heavy crowd of 600 including secretaries of state past and present, Colin Powell and Condoleeza Rice.
President Bush danced, as did First Lady Laura Bush and their two daughters, Barbara and her newlywed sister Jenna, who is just back from her Hawaiian honeymoon, the guest says.
"The President looked pretty cool,” says the guests. “He was a good dancer. He was having a great time."
After the reception, the groom's parents, John and Maggie Hager, invited friends to join them at the Old Ebbitt Grill a few steps from the White House and a favorite hangout for politicos.
