388 Reps are going to be escorted out of The House next month. The bill had to pass before this event happens.
>I don't understand why this bill had to pass?
There will be a fair amount of chaos for awhile and it's possible nothing will be done in The House for months. This averts a gov shutdown. Not that I care.
>How many voted to certify AND voted for the omnibus?
Not sure. In any event:
How many is a quorum in the House of Representatives?
Therefore, in both the House of Representatives and the Senate, a quorum is a simple majority of their respective members (currently 218 in the House and 51 in the Senate).
If 388 are removed from their seats, there won't be a quorum for awhile. Nothing is going to get done. This averts a gov shutdown. Not that I care.
