President Trump must contend with the wrath of a wealthy ex-ally who may seek to undermine him politically. Mr. Trump has threatened to cut off Elon Musk’s billions in government contracts.

The New York Times defended its reporting on Elon Musk ‘s drug use, after he claimed that the publication was “lying” in its article that claimed he was, among other things, “taking so much ketamine, a powerful anesthetic, that it was affecting his bladder, a known effect of chronic use. He took Ecstasy and psychedelic mushrooms.”

As Mr. Musk entered President Trump’s orbit, his private life grew increasingly tumultuous and his drug use was more intense than previously known.

Taking to their respective social media platforms, Trump threatened to cut Musk’s government contracts, while Musk said Trump would not have won in November without him.
