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.

The billionaire, whose ties with the president have frayed in the past month, attacked GOP lawmakers backing the Trump’s spending bill while boosting its critics.

Tesla remains Musk’s best-known business, but its fortunes are less directly tied to the government than SpaceX, his rocket-building company.
