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

Musk has spoken about his prescription ketamine use in the past. Last March, he told journalist Don Lemon that he uses a “small amount” of ketamine about once every other week. The ketamine, he said, is prescribed by “an actual, real doctor.”

Mr. Musk, who says he will devote more time to his private companies, never came close to achieving his goal of cutting $1 trillion from the federal budget.

Elon Musk mocked The New York Times on Friday over new reporting about his alleged drug use and "family drama." PETER DOOCY, FOX NEWS: The president mentioned that you had to deal with all the "slings and arrows" during your time at DOGE.
