Donald Trump and Elon Musk exchanged back-and-forth insults online after a disagreement over the president's spending bill. Here's a complete timeline of Donald Trump and Elon Musk's friendship, including why they are now feuding.

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.

Musk backed former Secretary of State Hillary Clinton in 2016 and former President Joe Biden in 2020 but worked with Trump at times during his first term. He said in 2017 that simply attacking Trump would "achieve nothing," calling for "open channels of communication" with the president.
