(FILES) In this file photo taken on June 12, 2018 US President Donald Trump (R) walks out with North Korea's leader Kim Jong Un (L) after taking part in a signing ceremony at the end of their historic US-North Korea summit, at the Capella Hotel on Sentosa island in Singapore.
Reports that North Korea intends to secretly maintain some of its nuclear stockpile and production facilities raised questions on July 1, 2018 about President Donald Trump's insistence that the North was "no longer a nuclear threat," after his historic summit in Singapore. The Washington Post cited four unnamed US officials who, it said, had seen or been briefed on new intelligence findings that point to preparations for deceiving the United States. / AFP PHOTO / POOL / Anthony WALLACE
