From Change.gov:
The night before the presidency changes hands on January 20th, President-elect Obama will host a series of bipartisan dinners honoring Senator John McCain, General Colin Powell, and Vice President-elect Joe Biden.
All three honorees have built reputations as leaders who work across the aisle to progress our country.
Congressional leaders from both sides of the aisle, along with everyday Americans, will attend the dinners at the National Building Museum, Union Station and the Hilton Washington.
