After Elon expressed regret for some of the tweets, the White House said Trump was thankful and "appreciative" of his apology — however, it sounds like he's certainly not forgiving or forgetting, as a source tells People the two remain on "so far from good terms."

The allegations against Elon Musk suggest he was a frequent user of ketamine, ecstasy, psychedelic mushrooms, and Adderall while he provided advice to the President. Per reports, he carried a pill box with him and allegedly took drugs daily as of last year.

Elon Musk took to social media on Tuesday to show off what appeared to be a negative urine test for multiple substances including ketamine, cocaine and amphetamines.
