Shah also refused to rule out the possibility of Trump traveling to Pyongyang to meet the North Korean leader.

"I don't think that that's, you know, highly likely but again, I'm not going to rule anything out," Shah told Karl.

“[It’s] a lot less important about where they meet than the substance of the meeting," Pompeo said on "Fox News Sunday."

"The location of the meeting, the timing of the meeting, the president and the team will figure out," he continued.

The White House announced on Thursday that the president would accept an invitation to meet face-to-face with Kim, a historic first for a sitting U.S. president. South Korean officials said that North Korea was willing to cease its missile testing while talks with the U.S. are ongoing.

The two countries have exchanged insults and threats throughout Trump's first year in office, while Kim continued to defy the global community by testing a series of intercontinental ballistic missiles.

Trump said on Saturday that he is anticipating a successful meeting with Kim.

"I think North Korea is going to go very well," he said. "I think we will have tremendous success ... they promised they wouldn't be shooting off missiles in the meantime, and they're looking to de-nuke. They're gonna be great."
