The on-again, off-again summit between the US and North Korea has caused apparent confusion within the White House, as the president and his senior staff are now saying two different things—first, about whether a meeting between the two heads of state would be productive, and then about when it might be scheduled.

On Thursday President Donald Trump canceled the summit that had been planned for June 12. He pointed to the “tremendous anger and open hostility” from the North Koreans after John Bolton, Trump’s national security adviser, suggested that the US would apply the “Libya model” in its approach to North Korea and its nuclear weapons stockpile. (He was referring to the late Libyan dictator Muammar Gaddafi agreeing to give up nuclear ambitions in 2003 only to be murdered by US-backed rebels in 2011.) Then Trump said that Libya was not the model for North Korean nuclear disarmament, but Vice President Mike Pence made reference to Libya again on May 21, which provoked North Korean officials to call Pence a “political dummy” and threaten a “nuclear-to-nuclear showdown.”

A day after canceling the summit, Trump told reporters that the White House was again talking to the North Koreans and that the summit might happen on June 12 after all. In describing the reversal, the New York Times cited a “senior administration official” as telling reporters that “even if the meeting were reinstated, holding it on June 12 would be impossible, given the lack of time and the amount of planning needed.”

That drew the ire of the president on Saturday who slammed the Times on Twitter:

Unlike what the Failing and Corrupt New York Times would like people to believe, there is ZERO disagreement within the Trump Administration as to how to deal with North Korea…and if there was, it wouldn’t matter. The @nytimes has called me wrong right from the beginning! — Donald J. Trump (@realDonaldTrump) May 26, 2018

The Failing @nytimes quotes “a senior White House official,” who doesn’t exist, as saying “even if the meeting were reinstated, holding it on June 12 would be impossible, given the lack of time and the amount of planning needed.” WRONG AGAIN! Use real people, not phony sources. — Donald J. Trump (@realDonaldTrump) May 26, 2018

As pointed out by freelance journalist Yashar Ali, the official that Trump says “doesn’t exist” was actually Matt Pottinger of the National Security Council, and Pottinger’s statement was recorded (and subsequently posted by Ali). The White House routinely organizes calls during which administration officials brief the reporters on a given topic.

The Times noted that various officials within the Trump administration have different opinions on how to address the North Korean nuclear situation. Whereas Pence and Bolton spoke publicly about decapitating the North Korean regime, Secretary of Defense James Mattis prefers diplomacy.

Trump may be learning that resolving the North Korean situation isn’t as easy as he’d assumed. The tension between the US and North Korea is decades old and “complicated,” as this recent Mother Jones video explains:
