Trump implored DOGE to look into the matter as his weeks-long feud with Musk came to another head.

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.

Musk, who supported Trump's campaign and also served as an adviser to the White House, has criticized the tax and spending bill the president is pushing.
