Watch live: United CEO testifies at congressional hearing after passenger dragging

The CEO of United Airlines, Oscar Munoz, will testify before the House Transportation and Infrastructure Committee during a hearing Tuesday, less than a month after a shocking video of a passenger being dragged off a flight left United embroiled in controversy. Watch the hearing live in the player above.

David Dao was removed from United Express flight 3411 on April 9 to make room for crew members. Several lawmakers have proposed legislation in the aftermath of the incident, to potentially bar airlines from overbooking flights or to prevent airlines from removing a passenger who is seated aboard a plane.

Dao, who suffered a concussion and lost two teeth in the incident, has reached a settlement with the airline, according to his lawyer.

United earlier apologized to Dao and refunded fares to other passengers on the flight. United also adopted 10 policy changes, including no longer asking police to remove passengers from flights for reasons other than safety or security.
