Seat mates Ernst and Arkansas Republican Tom Cotton were the chattiest in the chamber early on, despite the stern daily warning from Sergeant-at-Arms Michael C. Stenger to "keep silent, on pain of imprisonment."

Ahead of the dinner break, Thune sat back in his chair gripping the pillars of his armrests and chewing deliberately while listening to the presentation. He then loosened up his neck making a circular motion.
West Virginia Republican Shelley Moore Capito neatly folded a red shawl and placed it on her lap.
At least 27 Senate desks were empty when Demings took the floor following a "15-minute" break that only a Senate time-keeper could argue was respected.
Around two-and-a-half hours into the Democrats' presentation, 10 senators stood behind their desks or near the doors as Capitol Police outside the chamber prepared the halls for the Senate's first recess of the day.
