Musk was taking all the attention and jumping about like a dick.

First rift was musk was going to get classified briefings on China and Trump put a stop to it.

Also Musk had a fall out with Bessent and Trump sided with Besset.

Also rumoured he fucked Steven Millers wife (who is a left and would blacken a right eye with a hook).

Nothing to do with the bill at all IMO. He does not give a single fuck about that. Just a pain point he knows he can drive a wedge through a big part of Trumps base.
