The secretary of state also said "there will be in-depth verification" of the denuclearization process, rebuffing critics of the joint statement signed by Trump and Kim that was light on details relative to timeline, process and verification of North Korea's disarmament.
Sen. Bob Corker, R-Tenn., said Tuesday that he wants Secretary of State Mike Pompeo to brief senators on the substance of what the two nations discussed, including whether US troops stationed on the Korean Peninsula would remain. After a day filled with smiles and handshakes watched around the world, the USA "committed to provide security guarantees" to North Korea.

President Donald Trump on Wednesday morning declared an end to the North Korean nuclear threat. Trump left the summit early, and as he flew to Singapore, he tweeted that he was yanking the US out of the group's traditional closing statement.
When relations between the US and the DPRK thawed slightly between 1990 and 2005, a repatriation agreement allowed 229 sets of remains to come home to American families. It called the summit "dumbfounding and nonsensical", and said it will allow North Korea to permanently maintain its nuclear weapons programme.
Mr Trump said scrapping them will save a "tremendous amount of money", but he added that they could be reinstated if co-operation from the North declines.
"Before taking office people were assuming that we were going to War with North Korea".
"I am. confident they understand that there will be in-depth verification", Pompeo said, adding that further US talks with North Korea on how and when it will end its nuclear program will resume "sometime in the next week". "No longer - sleep well tonight!" -South Korean military drills and move forward with the plan to remove the 28,500 American troops stationed in Seoul.
"I believe it's a rough situation over there, there's no question about it and we did discussed it today pretty strongly", Trump said in response to a question from ABC News chief White House correspondent Jon Karl. "I am confident that they understand what we're prepared to do, the handful of things that we're likely not prepared to do".More news: Cyberpunk 2077: Main Character, Customization, Exploration Revealed

Kim may have best summed up the surreal quality of what was happening when he said that many of those watching will think it's a scene from a "science fiction movie".
"We are ready to write a new chapter between our nations", Trump told reporters after the much-talked about summit - the first between a sitting United States president and North Korea's top leader.
On the day before the meeting, weeks of preparation appeared to pick up in pace, with US and North Korean officials meeting throughout Monday at a Singapore hotel.
During his return, Trump spoke with South Korean Prime Minister Moon Jae-in and Japanese Prime Minister Shinzo Abe. Pompeo, the former Central Intelligence Agency director, then plans to fly to Beijing to update the Chinese government on the talks.
If he was forced to negotiate by USA pressure, it certainly wasn't obvious.
However, many South Koreans rushed to express their awe of Tuesday's events.
They hold joint military exercises every year that infuriate Pyongyang, which has long demanded an end to the drills and often responds with actions of its own, ratcheting up tensions. He said North Korea is likely to consider Trump's decision a temporary measure while it remains in negotiations with Washington.
Washington and Seoul are security allies, with 28,500 United States troops stationed in the South to defend it from its neighbour which invaded in 1950. The next scheduled major exercise, involving tens of thousands of troops, normally would be held in August.
