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.

Members of both parties on Capitol Hill have praised his efforts to strike a deal with Kim, though some Democrats worry the North Korean dictator is playing Trump and has no intention of giving up his atomic arms while getting concessions on sanctions and other things from Washington.

The story in the New York Times concerning North Korea developing missile bases is inaccurate. We fully know about the sites being discussed, nothing new – and nothing happening out of the normal. Just more Fake News. I will be the first to let you know if things go bad!
