I find this AP report quite confusing:
Johnson resorted to moving the bill through an expedited process that requires a two-thirds majority for passage. That’s because Republicans were unlikely to even muster the simple majority needed to set the terms for the bill’s debate. Such a procedural vote is generally a routine matter, but has become problematic for the current Republican majority, which can generally afford to lose only three Republicans on party-line votes. The vote for more Israel aid was 250-180, well short of the two-thirds threshold necessary for passage.
According to Wikipedia, the current threshold for majority in the House is 218. So, if they could get 250 votes to (not) pass the bill (because of the 2/3 threshold), why could not they "muster the simple majority needed to set the terms for the bill’s debate"?
CNN's coverage of this isn't much more illuminating:
Because of resistance among members of the conservative House Freedom Caucus, House Speaker Mike Johnson had been forced to bring up the bill under a procedure that requires two-thirds majority of the House to approve it.
How could (presumably) only a handful of Freedom Caucus guys "force" Johnson to seek a 2/3 majority?
FWTW, another source mentions that
Johnson told reporters he plans to bring the bill up next week under a process that requires only a simple majority.
So why couldn't he do that this week?
