Today Sen. John McCain (R-Ariz.) made an appearance on the daytime program "The Ellen DeGeneres Show," and the topic quickly turned to the issue of same-sex marriage. The issue arose after Ms. DeGeneres revealed on her show last Friday that she will be marrying her parter, Portia de Rossi. The marriage announcement came a day after the California Supreme Court overturned a ban on gay marriage. View video here.

Here's a partial transcript of the conversation:

Is there something in the water at NBC that gives its TV talent restless leg?

MSNBC's Chris Matthews is the latest journo to bust a move, on the March 19 "Ellen DeGeneres" show.

Looks like colleague David Gregory has some fresh competition, but I'm confident the NBC White House correspondent has what it takes. After all, he can get down to anything from Hilary Duff to Mary J. Blige.

That Hillary Clinton -- what a card!

According to an email I've received from her campaign, the intrepid Hillary is venturing into the lion's den, with TV appearances scheduled tonight on Letterman and September 4 on the Ellen DeGeneres show. Daring stuff!

In any case, according to the email:

Ellen is soliciting questions from her viewers to ask of Hillary, and we want to turn it around on her. So if you have a question for Hillary to ask Ellen, submit it here.
