The very moment the text of the bill was released, Republican senators held a press conference on how there was zero chance of it being passed: https://www.youtube.com/watch?v=Zf4EzoWR944
Here is the Speaker talking about the same: https://www.youtube.com/watch?v=Ii0tl8d5G3g
Despite what you may have been led to believe, Republican senators actually do have agency.
I didn't say that ALL Republicans supported it in hive-mind lockstep. I said "this bill was championed and lauded by the Republicans".
You linked to a video where 6 of the 49 Republican senators hold a mini-conference complaining about how they don't agree with their party's leadership. That doesn't refute the statement that "this bill was championed and lauded by the Republicans" if most Republicans champion and laud the bill.
Once again, I'll repeat: This was only 8 months ago. We remember how the bill was expected to pass before Trump told them not to.
And Trump specifically said that the reason not to was that he wanted to the border to remain weak so that he could nail the Democrats on it.
