Tesla for years had more repeat U.S. customers than any other major automotive brand but its loyalty has plunged since CEO Elon Musk endorsed President Donald Trump last summer, according to data from research firm S&P Global Mobility shared exclusively with Reuters.

Elon Musk hit back at President Trump’s claim that he didn’t want to strip the mogul’s companies of his government subisidies. Trump seemingly extended an olive branch after the public falling out between the two by denying reports that he had it out for Musk.

Tesla's board approved a compensation package for Elon Musk worth about $29 billion in order to keep the chief executive focused on the company.
