I had heard second hand that at least one Senator (the Maine babe) doesn’t want to end the 30 hour rule...and that’s probably all that’s needed to keep it in place.
If true, McConnell could at least tell us, instead of looking like an oaf - but maybe he simply doesn’t care, at this point.
IOW, it's about a one day delay at most, and is NOT the source of months-long delays in confirming Trump's judical nominees.
