Sen. John McCain (R., AZ) announced that he will be a candidate for President of the United States in 2008 during Wednesday tonight's taping of the Late Show with David Letterman on CBS.

"The last time we were on this program, I'm sure you remember everything very clearly that we say, but you asked me if I would come back on this show if I was going to announce," Sen. McCain told Letterman. "I am announcing that I will be a candidate for President of the United States."

McCain said although this was the announcement of his candidacy, a formal announcement will be made in April. "This is the announcement - you know, you drag this out as long as you can," Sen. McCain said to laughter from Letterman and the audience. "You know what I mean? You know, you don't just have one rendition. You've got to go over and over...This is the announcement preceding the formal announcement."

Letterman later asked Sen. McCain if he would consider "the possibility President/Vice President, that kind of a thing, you divide that sort of deal up. You're not interested in splitting that?" Sen. McCain said, "Well, you may remember that in the last election there was some conversation about me being Vice President of the Untied States, it wasn't clear which party," which garnered laughter from Letterman and the audience. "And I was on one of the shows and the guy said, 'Well, what's this about you being Vice President of the United States?' I said, 'You know, I spent all those years in a North Vietnamese prison camp, kept in the dark, fed scraps - why the heck would I want to do that all over again?'"
