Former President Donald Trump reportedly shared details about Americas nuclear submarine program with an Australian billionaire, who then went on to tell journalists, foreign officials and others about the sensitive information, according to multiple reports.

ABC News first reported that special counsel Jack Smith had learned about Trumps disclosure to the billionaire a cardboard magnate named Anthony Pratt as part of his investigation into the former presidents handling of classified documents. Trump allegedly told Pratt several government secrets about the submarines during an event at his Mar-a-Lago club and residence in Florida, where the billionaire is a member.

Pratt reportedly told prosecutors and FBI agents that he brought up the submarine fleet in April 2021, after Trump had left the White House. The former president then revealed the supposed number of nuclear warheads that are on board U.S. submarines at any time and how close the vessels can get to a Russian submarine without detection.

The billionaire, ABC News added, shared that information with at least 45 people, including three former Australian prime ministers, a half dozen journalists and other foreign officials. Australia recently inked a deal with the United States to spend up to $245 billion over the next three decades to build a fleet of nuclear-powered submarines.

Its unclear if the details were accurate or if they were bluster or exaggerations, but ABC News reported that Pratt was informed by investigators not to share the numbers he was reportedly given.
