President Donald Trump on Tuesday denied that North Korea is moving ahead with its nuclear weapons program despite a pledge from Kim Jong Un to freeze all such work.

Citing satellite images, the New York Times reported Monday that Kim is continuing work at sites he promised to Trump would cease while the two leaders — and, sometimes, their staffs — try to strike a denuclearization deal.

In a tweet, the commander in chief called the Times report “inaccurate”and “Fake News,” and claimed U.S. officials “fully know about the sites being discussed, nothing new – and nothing happening out of the normal.”

Trump last week said he expects to meet again one-on-one with Kim early next year.
