Washington (CNN) President Donald Trump falsely claimed again on Tuesday that North Korea continues to send the US the remains of American troops who died in North Korean territory during the Korean War.

Speaking to reporters in the Oval Office, Trump was asked about his latest letter to North Korean leader Kim Jong Un . Trump said it was a "nice" response to Kim's birthday message to him, then began touting the progress he said he has made in relations with North Korea.

The President accurately cited North Korea's decision to pause nuclear testing and to release American detainees. But then he returned to one of his repeated inaccurate statements.

"We've had, as you know, the remains of the heroes, our great heroes from many years ago -- that's coming back, and coming back as they find them, and as they find the sites and the graves, and they're sending them back," Trump said.

Facts First: While North Korea returned some remains last year, it is no longer doing so. The US military : While North Korea returned some remains last year, it is no longer doing so. The US military announced in May that the remains program had been suspended for the rest of the 2019 fiscal year because North Korea had stopped communicating with the US agency responsible for the effort.
