Elon Musk had advocated ending the $7,500 tax credit for buyers of Tesla and other automakers’ EVs. But with the end of that credit included in the the “big, beautiful bill,” he and the now financially struggling Tesla are arguing for its continuation.

Elon Musk’s bitter falling-out with President Trump could be costly for Tesla. As long as he is persona non grata in the Trump administration, Mr. Musk, the chief executive of Tesla, will struggle to persuade Republicans not to gut climate policies worth billions of dollars to the electric car and battery company.

"Elon is upset because we took the EV mandate ... which was a lot of money for electric vehicles," Trump said Thursday in the Oval Office. "They're having a hard time, the electric vehicles. And they want us to pay billions of dollars in subsidy. And, you know, Elon knew this from the beginning."
