Dao was randomly selected to de-board the aircraft when United Airlines personnel needed extra seats in order to travel for work. A Twitter user named Joya Cummings claimed to be a passenger on the flight. Cummings uploaded a video on Tuesday morning that showed what happened before Dao was removed.
