Celebs sound off on United Airlines after passenger incident

— -- Hours after video surfaced of a United Airlines passenger being forcibly removed from his seat on an overbooked flight, celebrities began sharing their opinions of the incident on social media.

United's CEO, Oscar Munoz, released a statement on Twitter Monday, saying he apologizes "for having to re-accommodate these passengers" and noted that the airline is investigating the incident.
