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

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.

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.
