This video is a closeup from a video shown during the GA election fraud hearings wherein testimony was made that ballot workers cleared the room of observers by claiming they were done counting ballots for the evening and then proceeded to start counting ballots that were in containers that were hidden from the view of the observers.

This video highlights additional potential fraud. It is a small section of the video that appears to show two ballot workers each passing a single stack of ballots through the tabulation machines three times in less than two minutes.
