Last week's meeting between Trump and Kim broke down over what the Americans said were North Korea's excessive demands for sanctions relief in exchange for a limited offer to shut down its ageing main nuclear complex in Yongbyon.
During the House Oversight Committee hearing, Cohen, who has turned on Trump and has pleaded guilty to lying to Congress earlier to protect Trump, was harshly critical of his former boss, calling him a racist, a con man and a cheat. Although the former congressman said he didn't like that Cohen's testimony was scheduled to coincide with Trump's meeting with Kim, he didn't believe it had any impact on the outcome. "I wasn't able to watch too much because I've been a little bit busy, but I think having a fake hearing like that and having it in the middle of this very important summit is really a awful thing". "I consider it a success defined as the president protecting and advancing American national interest", Bolton told CBS' Margaret Brennan. At a news conference last week, the California Democrat suggested that it should not have taken Trump so long to recognize that Kim is not serious about denuclearization.
The issue, Bolton said, was whether North Korea would accept what the president called "the big deal, which is denuclearize entirely under a definition the president handed to Kim Jong Un".

The Democratic head of the House Intelligence Committee Adam Schiff called the entire summit a "spectacular failure" and said Trump made things worse with his comments about Otto Warmbier.
President Trump has been accused of siding with the likes of Kim, Russian President Vladimir Putin, and Saudi Arabia Crown Prince Mohammed bin Salman amid allegations of brutality, human rights abuses, and even murder - which have been denied for their part. He also told CBS's Face the Nation, "The president held firm to his view". The United States and South Korea have suspended a number of military exercises since the first summit previous year between Kim and Trump to encourage talks with North Korea.
"We were looking at ways to tighten it up, to stop for example the ship to ship transfers that the North Koreans are using to evade the sanctions, to talk to other countries to make sure they tighten up on North Korea".
Moon lauded both sides for having talked about the complete demolition of North's Yongbyon nuclear facility under the observation of American experts, saying the scrapping of Yongbyon would mark an "irreversible" step in North Korean denuclearization.
The maneuvers have been a perennial target of North Korean fury - condemned by Pyongyang as provocative rehearsals for war.
