White House manages expectations for second Kim summit

President Donald Trump is trying to manage expectations for his second summit with North Korean leader Kim Jong Un, predicting a "continuation of the progress" made last time.

Trump tweeted Sunday that he was leaving early the next day for the meeting in Hanoi, Vietnam, adding a tantalising nod to "Denuclearization?"
He also said Kim knows that "without nuclear weapons, his country could fast become one of the great economic powers anywhere in the World."
Secretary of State Mike Pompeo said on "Fox News Sunday" that he was hoping for a "substantive step forward." But, he cautioned, "it may not happen, but I hope that it will."
Said Markey: "Nothing is clear, and I think as a result we could run the risk that Kim is given concessions which are not accompanied by real concessions that the United States is receiving in return from Kim and his regime."
Trump pushed back against his critics on Twitter Sunday, saying: "So funny to watch people who have failed for years, they got NOTHING, telling me how to negotiate with North Korea. But thanks anyway!"
Pompeo said he believes North Korea remains a nuclear threat, though Trump tweeted after the Singapore summit that "there is no longer a Nuclear Threat from North Korea."
