Donald Trump’s top adviser Elon Musk has openly threatened Pentagon employees who may have leaked information that the tech billionaire was due to get a briefing on a potential American war with China.

The story, published by the New York Times on Thursday evening U.S. time, said that — according to anonymous American officials — the Pentagon planned to brief Musk on Friday about the U.S. military’s plan for any war that might break out with China.

After the story went live, the planned meeting was confirmed by Pentagon officials and President Trump — but both denied that the session would discuss military plans involving China.
