Most of that pressure is artificially created to get lawmakers to sign bills without reading. Creating a sense of urgency is a classic scamming technique and it's used extensively in the political world, because most politicos are really nothing more than con artists.

Political pressure? They're appointed for life, literally what consequences are there to pushing back? Honestly the senate is such a waste of money. They're trying to play both sides of this issue to the benefit of no one.
