Trump and Musk to speak on Friday after alliance descends into public feud

Shares in Musk’s Tesla closed down over 14% on Thursday, losing about $150 billion in market value in the largest single-day decline in value in its history.

Donald Trump’s aides scheduled a call between the US president and Elon Musk for Friday after a huge public spat that saw threats fly over government contracts and ended with the world’s richest man suggesting Trump should be impeached.
