the floor for a vote. I believe it will need 217 votes to pass the House. That means 2 out of Marjorie Taylor Greene, Lauren Boebert & Nancy Mace will have to vote for it. You would hope they will all vote for it given they signed the petition, but there's no way we can completely trust any of those 3.
Assuming it does pass, it goes to the Senate. I'm not sure how/when it can be forced to be put up for a vote there. If the vote happens, they need 13 Republicans to vote for cloture (assuming cloture is invoked). Then it would need 4 Republicans to vote for the bill. It would seem highly unlikely to have enough Republicans vote as needed to pass the Senate.
But let's assume it does pass the Senate. Trump then needs to sign it which there is zero chance of happening, so this bill will never get implemented, regardless. However, it's still important to put pressure on the Republicans. The public outcry to release the files is already remaining loud (even while the administration does everything humanly possible to divert attention). Passage of this bill in the House will make the public outcry even louder.
