Our middle son's wife runs the commissary/mess at one of the smaller studios in Hollywood and a couple of weeks ago she heard a rumor that there were people looking for 'extras' to fill seats at the upcoming Trump rally in Phoenix. Now she's not sure if anyone actually answered this 'casting call', but it's not the first time that she had heard of something like this happening, including going back to the time of the campaign itself.
We know that there must have been some problems with that rally since the guy who has always managed the field operations related to these campaign rallies was 'relieved' of his duties immediately after the recent event in Phoenix. It seems that he didn't quite deliver the crowd that he had been paid to deliver nor did he keep the media from learning about the actual turnout:
