A hot mic caught a Hillary Clinton staffer complaining that her boss was late to an event

Like many busy people, Hillary Clinton is sometimes late. For example: Clinton recently ran somewhat late to a campaign event in Iowa, leaving a number of her staffers at a loss as to how to stall. One staffer in particular was worried, which was to be expected. What wasn’t to be expected was the staffer expressing her exasperation into a live microphone, which was picked up by a television camera.
