It's John McCain Day at the White House, NBC's John Yang notes.
President Bush will welcome him and wife Cindy will at the North Portico -- the spot where foreign leaders arrive for State Dinners -- at noon in front of live television cameras. After lunch in the President's private dining room, Bush and the presumptive nominee will appear together in the Rose Garden for the official embrace--the President's endorsement.
The president has already said that McCain is a true conservative and pledged to campaign for him. White House political officials acknowledge that Bush's unpopularity with moderates and independents -- the swing voters McCain would need to win in November -- makes the embrace tricky. Better to do it early and get it over with. And Bush remains popular with the Republican base, so the president can help with party unity and raise money.
