They certainly could have just done the PBM reforms in a separate bill instead of shoving it into something else…but then they potentially wouldn’t be able to get their own choice cuts of pork passed.
Anyways, seems odd to blame Musk directly for that even if his tweet did kill the bill.
Musk tanked a bill he obviously didn't read with zero plans for its replacement. So instead of a $1.7 trillion bill in December, we get roughly the same bill (that's what a continuing resolution is) plus $100bn in giveaways in March minus the PBM reforms.
Musk killed PBM reform. The fact that he was too high to know what he was doing isn't exactly redemption.
