U.S. federal agents were looking for documents relating to nuclear weapons when they raided former President Donald Trump’s home in Florida this week, the Washington Post reported on Thursday. It was not clear if such documents were recovered at the former president’s Mar-a-Lago resort in Palm Beach, the Post said. Trump said on Friday on social media that the “nuclear weapons issue is a hoax”, responding to the Post report.

The U.S. Justice Department asked a judge on Thursday to make public the warrant that authorised the FBI search of Mar-a-Lago, after Trump, a Republican, portrayed it as political retribution. The request means the public could soon learn more about what investigators were looking for during the unprecedented search of a former president’s home.
