Yes i seen that video of buses lining up to pick up what is likely congress. Remember when the train of mostly republicans that where moved out of the capital into a safe location. This is likely something to like that event. Moving congress to a safe location
I see no indication they where "arrested" in that video.

The arrests weren’t seen in the livestream, but it was in the article that the woman was reading. It was at the 0:54 second mark.

It’s in some article, but there is no confirmation of that article.
