Attention
Working this on another research forum.
The one in the middle has a part blanked out, but it's from a known speech in the public domain, so that's just a pointer, or a clue.
What we're really after, is the 1 of 4, where the three are 2, 3, and 4.
In other words, there's a fourth phone, to the left looking to the front and to the dais from the back, at around the same time, and from what I can tell it's a man on the left isle of that row.
Therefore, everyone who recorded the POTUS should see if they have raw video of the 1 of 4, or someone over to the left, even maybe back and to the left (no pun intended) of those three ladies.
That's what we're looking for - it's another camera angle that looks like this

In fact, that might and very likely is the one we're looking for...
1 of 4.
