The clock appears to have run out on the special session, but the final vote on a piece of controversial abortion legislation is still in dispute.

Amid deafening shouts from the gallery, the Texas Senate attempted to vote on Senate Bill 5, which would would give Texas some of the strictest abortion regulations in the country if passed.

The vote came after an hours-long filibuster by Democrats. Sen. Wendy Davis talked for more than 10 hours Tuesday to block the bill. Senate rules required her to stay standing without any food, water or assistance from others. She also had to stay on topics related to the bill.

Republicans eventually ended the filibuster by pointing out technicalities in the procedure, but Democrats spent the next two hours challenging the rulings. Shortly before midnight, spectators in the Senate gallery started yelling so loudly that Senators couldn’t hear to conduct business.

While DPS officers cleared the gallery, Lt. Gov. David Dewhurst called for a vote on the bill. Democrats say the vote came too late — after midnight — and therefore after the session had ended, but Republicans claim the bill passed.

The legislature’s online record-keeping system currently shows that the vote happened at some point before midnight. However, shortly before 1:30 a.m., Democratic Rep. Joe Deshotel Tweeted this photo, which appears to show that the vote happened after the midnight deadline and was later changed.
