Former commander of the Pacific Command Harry Harris, Mr Trump's pick for U.S. ambassador to South Korea, told United States lawmakers last week that North Korea continues to be a nuclear threat and that major military exercises should be paused to give Mr Kim a chance to prove whether he is "serious".
They also suggest Americans may not be familiar with key facts about the summit; according to Monmouth, for instance, less than half of those polled knew Trump had agreed to cease military exercises with South Korea in a major concession to Kim.
Earlier this month, U.S. Defense Secretary Jim Mattis said the status of U.S. troops in South Korea would not be on the table during the meeting between Trump and Kim.
"We will stop the war games which will save us a tremendous amount of money", Trump told reporters after meeting with Kim.
Trump went on to say that the denuclearization deal was celebrated across Asia.
In response to Kim's promise on denuclearization of Korean Peninsula, Trump assured full security to North Korea and there will be no attack with nuclear or conventional weapons.
Trump also defended his decision not to press Kim during the summit over Pyongyang's human rights abuses, arguing that he did so because preventing a nuclear war is a more pressing matter. "I sometimes say the "denuking" of North Korea, and those are attractive words", Trump said in the video.
Trump boasts North Korea stand-off 'largely solved'
White House staff said Trump's seat-of-the-pants changes on the day of the summit undercut their plans to roll out the agreement. The US has stationed combat troops in South Korea since the end of the Korean War and has used them in a variety of drills.

Exhaust-ing ordeal: Woman gets head stuck in tailpipe
A woman at a music festival had an exhaust-ing ordeal after getting her head stuck in a truck's tailpipe. So it's kind of expected when it's blasted on the internet that you're going to get negative comments ...
While the agreement fell short of outlining concrete measures that would lead to Kim giving up his nuclear weapons program - the stated long-term goal of USA negotiators - it gave Trump and Kim a piece of paper to point to as a sign of progress and a symbol of goodwill.
He's very smart. Kim Jong Un - amusing guy.
Recently, Park filmed a video op-ed imploring Trump to do the right thing when he meets Kim Jong Un. Speaking about the highly-contested dictator, the current Commander in Chief notes how "he's the head of the country, and I mean he's the strong head". Don't let anyone think anything different.
"That's a very important thing", he said. "He speaks and his people sit up at attention". Pressed on how close North Korea is to that stage, he added, "very close".
Trump claimed that the meeting brought in peace to the world.
"Before taking office people were assuming that we were going to War with North Korea", Trump tweeted a day after the summit. "North Korea has great potential for the future!"
But it remains in possession of fissile material for a dozen to 60 nuclear bombs, independent experts say. "Nauseating to see Trump stiff our allies in Canada and then praise Kim while saluting his generals". Officials have not verified reports that North Korea may have demolished a stand used for missile-ejection tests in May.
