The bromance may be over, but the president and Tesla CEO Elon Musk keep showing signs of backing off from last week’s very public feud. On Monday, Trump said “I’d have no problem with it,” when asked if he would be willing to speak with Musk.

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.

The spectacular breakup of Donald Trump and Elon Musk could soon get far worse for the Tesla CEO—while doing little good for the U.S. president. Some political pundits have portrayed last week’s blowup as merely yet another exit by a disgruntled Trump ally.
