Transcript for Democrats questioning deals made during Trump-Kim summit

process of getting access to millions of his records. Thank you. The president, beating us back home. And declaring an historic victory. Declaring that North Korea is no longer a nuclear threat. But what did the U.S. Offer? And did we get enough in return? No concrete timeline on when the nukes will be destroyed, and how it will be verified. Here's Kyra Phillips from the white house. Reporter: President trump landed back in the United States today declaring, "There is no longer a nuclear threat from North Korea." Great three days. Reporter: "Everybody can now feel much safer than the day I took office," he tweeted. But Kim Jong-un still has his nukes. Okay. Reporter: And the joint statement he signed in Singapore did not indicate how and when he would give them up. It also did not say that denuclearization would be "Verifiable" and "Irreversible." I read the statement and it's difficult for me to see if something was actually agreed to or not. Reporter: Arriving for talks in South Korea today, secretary of state Mike Pompeo said he expects major disarmament from the north within the next 2 1/2 years. He bristled when reporters pressed him on the joint statement, calling their questions "Insulting, ridiculous and quite frankly ludicrous." We have developed a very special bond. So people are going to be very impressed. Reporter: Just as the president was declaring victory, so, too, was North Korea. State television reporting that trump pledged to "Lift sanctions as mutual relations improve through dialogue and negotiation." Not exactly what president trump said in his news conference. The sanctions will come off when we are sure that the nukes are no longer a factor. Reporter: North Korea's newspaper also trumpeting the president's announcement that the United States will no longer engage in military exercises with South Korea. We're not going to play the war games. Reporter: South Korea caught off-guard. Some saying the president gave a lot more than he got. This is not "The art of the deal," but the beginning of "The art of concessions". I believe he wants to get it done. You trust him? I do. I think he trusts me, and I trust him. Kyra, before the summit, Mike Pompeo said that North Korea must take steps to remove their nuclear program, but that language was not in the agreement. Reporter: We're waiting for the specific and verifiable steps where they will destroy their nuclear arsenal. Pompeo says they understand there will be in-depth investigation.
