I do not believe this was true. I've contacted Lauren (who says she was not in the courtroom) and sent her the screen shot. If the daughters were there, only the people inside the room could have seen them - it was not on the streamed feed. It's nearly all men, one older lady with short gray hair and one person whose gender I cannot determine, but looks male, sitting alone in the back row, along with a lady dressed in pink, with a pink hat (who I suppose could be a daughter, but she has the body of an older lady and doesn't look tall enough - back row, right hand side of court from Judge's eye view).
There was no going in and out of the courtroom during the hearing.
There are 5 total men in the picture. Everyone is socially distanced and masked, but the short lady in pink does not look like either daughter to me. And she shows no "emotional reaction" that I can see.
