An ordinary mortal knowing the rules of the Senate is an unlikely but the article says “bill.”
I wouldn’t call myself an expert, but I did stay at a Holiday Inn Express last night (and I’ve spent more time than I’d have liked on Capitol Hill). It probably was a bill, Sxxx whatever, was not up for a vote, but for unanimous consent, which is the only way a single senator could block the “vote”; by objecting to the unanimous consent motion.
