Tapper: Tell us what you're going to do when it comes to Area 51 [a Nevada Air Force base where top secret aircraft have been developed, and where alleged alien spacecraft are studied], and whether or not the U.S. government knows of aliens, should Secretary Clinton be elected president.

Podesta: What I've talked to the secretary about, and what she's said now, in public, is that if she's elected president and she gets into office, she'll ask for as many [UFO] records as the United States federal government has, to be declassified. I think that's a commitment that she intends to keep and that I intend to hold her to.

Tapper: Have you seen any of these documents? You were a White House chief of staff years ago.

Podesta: President Clinton asked for some information about some of these things, and in particular, information about what was going on at Area 51. But I think that the U.S. government could do a much better job in answering the quite legitimate questions that people have about what's going on with unidentified aerial phenomena, and the American people can handle the truth. So, they should just do a thorough search and open it up.

Tapper: What is the truth? Is there evidence of alien life?

Podesta: That's for the public to judge, once they've seen all the evidence that the U.S. government has.

Tapper: What do you think, personally?

Podesta: What do I think? I think there's a lot of planets out there.
