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.

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.

Ross Gerber said Musk's beef with Trump is a "disaster," and used the episode as an opportunity to sell more shares.
