The Pentagon says there are 301 generals and admirals whose nominations have been placed in limbo because of an indefinite "hold" by Sen. Tommy Tuberville, a Republican from Alabama, who wants the military to change its policy of reimbursing servicemembers for travel to get reproductive care, including abortions.
By the end of the year, the Pentagon says that number could swell to 650 generals and admirals who need Senate confirmation before they can assume their jobs. Any single senator can put a hold on nominations under Senate rules.
It's insane that one Senator has that much power and Tuberville is a unqualified, moron but ultimately I don't see this being a huge issue for the military. They will simply have those people fill those slots without the requisite rank or have another GO cover down and do that job. A good chuck are probably positions created solely so they can have a place to put those GOs anyway.
