Trying to block the infamous GOP-led elections bill at the heart of months of protests, Texas state Sen. Carol Alvarado began her filibuster just before 6 p.m. CT on Wednesday. By Thursday morning, Alvarado was still at it. She finished her speech at 9:00 a.m. CT—marking 15 total hours.

The Texas filibuster is particularly brutal: While they speak, senators cannot eat, drink, sit or lean on any surface, or use the bathroom. The senator must be continually speaking and the words discussed must be relevant to the bill.
