First post here so no idea how to format this properly
At 2:06 when the blue woman turns up you can clearly see that she says something discreetly to purple woman whilst trying to make it look like they don't know each other
From 2:46 purple woman starts getting ready for the handoff. I bet that's when she spots the guy walk in to the room. you can see her look at something off camera
At 2:55 purple is hyper aware of what's going on around her
At 3:07 she grabs her drink so that she can stop doing ballots and look around.
Look at purple woman's actions and body language from 3:06 to 3:14. that's the body language of someone about to do something they shouldn't and checking to see if there's anyone watching
Look at the way she moves that bag from 3:14 to 3:39. that's not the body language of someone doing something above board
4:09-4:13 woman in white grabs the usb from somewhere behind her. looks like it may have been brought by the woman in purple although i cant see where she gets it from exactly. 4:14-4:18 woman in white passes usb to blue woman 4:33-4:36 She discreetly slides the USB into the mans pocket.

This was posted on 4Chan with people there spotting the usb trade. I didn't see anyone mentioning that the woman in purple seemed to be involved too and maybe even the woman in yellow so wanted to post it here. The post on 4chan says that the woman with the braids in Blue is the same woman that was kicking out poll watchers later in the evening.
