Daily SumUp

Tech billionaire and senior Trump adviser Elon Musk has visited the Pentagon for briefings that have sparked debate after US media reported that he would be given an overview of American plans in the event of war with China.

President Donald Trump denied the reports, saying "China will not even be mentioned or discussed".

Musk himself called for the prosecution of officials he said had leaked "maliciously false information" to the New York Times, which first reported the story.

But the Pentagon visit represented an unusual level of access for the Tesla and SpaceX CEO, whose companies hold billions of dollars in federal defence contracts.
