I think OP meant to start the video at 11:57 mark, not 10:57. It's when POTATUS and whats-her-name start walking in.
There's bulletproof glass in front of and to the left and right of the speaking area, if you pause the video around the 11:15-11:18 mark you can see it. The one side is catching the reflection of Independence Hall so you can't see them as they walk behind it. Maybe that's the green screen being referred to?

Yeah I noticed that as well. But I think they are angled in a way where the people won't show up? I dunno?
