#TrumpVsMusk WASHINGTON, July 1 (Reuters) - U.S. President Donald Trump on Tuesday threatened to cut off the billions of dollars in subsidies that Elon Musk's companies receive from the federal government, in an escalation of the war of words between the president and the world's richest man, one-time allies who have since fallen out.

The feud reignited on Monday when Musk, who spent hundreds of millions on Trump's re-election, renewed his criticism of Trump's tax-cut and spending bill, which would eliminate subsidies for electric vehicle purchases that have benefited Tesla, the leading U.S. EV maker. That bill passed the Senate by a narrow margin midday Tuesday.
