Donald Trump accused of sharing nuclear submarine details with Australian billionaire Anthony Pratt

"Former US president Donald Trump reportedly discussed "potentially sensitive" details of America's nuclear submarine program with an Australian billionaire.

"The American ABC news outlet reported that Mr Trump told Anthony Pratt the supposed number of nuclear warheads on US subs, and how close they could get to a Russian submarine without being detected.

"The conversation is said to have taken place at Mr Trump's Mar-a-Lago club in Florida, several months after he left office.

"ABC — which is not affiliated with ABC in Australia — also reported that Mr Pratt allegedly then shared the information with at least 45 people, including journalists and employees, as well as 10 Australian officials and three former prime ministers."
