Electric vehicles are expected to take a hit under the existing reconciliation budget proposal, but that isn’t the only provision that would seemingly hurt Elon Musk and his business if passed as written.

Tesla stock extended declines from earlier in the week as Trump and Musk traded words over the GOP budget bill, which Musk has described as an "abomination."

Tesla closed down more than 14% as a disagreement over the U.S. president’s budget bill turned nasty. After Musk said that Trump wouldn’t haven’t gotten elected without his help, Trump implied that he may turn the federal government against his companies, including Tesla and SpaceX.
