Biegun admitted that the United States and North Korea did not have an agreed definition of denuclearisation, but was blunt about USA expectations and said Trump had made clear he expected "significant and verifiable progress on denuclearisation" to emerge from the next summit.
However, he hammered in his concerns about Iran and stressed that their rocket testing is a unsafe sign.
Biegun's comments - his first public speech in five months as Pompeo's special envoy - offered a rare insight into the United States administration's approach to North Korea that officials had previously declined to provide.
Trump then delivered a slap to the face of USIC: "Perhaps Intelligence should go back to school!".
In a photo of himself surrounded by National Security Adviser John Bolton, CIA director Gina Haspel, and National Intelligence director Dan Coats, Trump claimed on Twitter that the fairly damning Senate intelligence hearing on Tuesday was "mischaracterized by the media". "I think that part of being a responsible public servant and a leader is to listen to different opinions and to understand and to ask in depth what is going on instead of putting them down".
USIC basically said Trump's decisions on a number of keys security and foreign policy issues are questionable, to say the least. They are testing Rockets (last week) and more, and are coming very close to the edge. For the first time they're talking about settling, they're talking about making an agreement, and we bring our people back home if that happens.
Trump continued: "Be careful of Iran. It's not that we don't take the threat with the gravity it requires", he said.More news: Mitch McConnell Slams Dem Bill to Expand Voting Rights
In a letter to Coats, Schumer called Trump's criticism of intelligence agencies "extraordinarily inappropriate" and said it could undermine public confidence in the government's ability to protect Americans. Iran is in financial chaos now because of the sanctions and Iran Deal termination. "Fortunately, we had a good Meeting and we are all on the same page". "I don't think it's a great secret", he told reporters at the White House.
President Donald Trump on Thursday teased expectations ahead of his next summit with North Korean leader Kim Jong Un, just as his top envoy is set to meet his North Korean counterpart to hammer out details of a new document for the two leaders to sign.
He also said that Kim committed to dismantle and destroy all of North Korea's plutonium and uranium enrichment facilities if the United States takes "corresponding measures".

Mr. Trump also tweeted early Wednesday morning that the USA relationship with North Korea is the "best it has ever been" just one day after his own intelligence chiefs testified on Capitol Hill that the regime still poses a threat.
Meanwhile, the envoy said Washington is willing to discuss "many actions" to improve ties and persuade Pyongyang to give up nuclear weapons, indicating that the "corresponding measures" demanded by the DPRK would be the subject of talks next week.
