A couple of observations while that video montage was played from inside the Senate chamber:

Collins took notes. Rand Paul appeared not to watch, but appeared to be writing in a notepad as it played. Some folks sat stock-still, like McConnell and Romney.

I didn’t see any visible reaction from Senators like McConnell and Lankford, who made appearances in the video.

On Dem side, Menendez and Reed sat on the edges of their seats, also perfectly still. Booker had a wrinkled brow and Gillibrand at one point had her head in one hand and just kind of looked in shock.

Anyway overall it was just a really bizarre and poignant video to see and hear play out, obviously on high volume in the chamber.
