The story of Dr. David Dao and United Airlines has dominated headlines since late Sunday. Dao was forcibly removed and injured after boarding a United Airlines flight out of Chicago. Footage went viral that showed Dao arguing with officers before he was removed from the overbooked flight.

On Wednesday, a new video began to circulate that showed the moments leading up to Dao's removal.

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.

“I won’t go,” Dao tells officers when they tell him he needs to leave the plane.

“I’m a physician, [I] have work tomorrow.”

When Dao is informed that he will be dragged off the flight, he threatens to sue United Airlines.

TMZ later uploaded a compilation of videos provided by Cummings.

“You can then drag me…I’m not going.” Dao says.

“I’d rather go to jail.”

Dao was ultimately taken off the flight and reportedly injured in the process.
