United apologizing after passenger shoved to floor at Houston airport

HOUSTON, Texas — United Airlines is apologizing after one of its employees pushed a 71-year-old man to the floor at a Houston airport.

The incident happened almost two years ago, but the video of the shove was just made public Tuesday, thanks to a Houston TV station.

In it, it appears that Alejandro Anastasia pushes 71-year-old Ronald Tigner to the floor and that Tigner was motionless on his back for nearly a full minute before a woman, who's been identified as another passenger, checks on him.

Anastasia was later charged with assault.

Tigner is suing United for more than $1 million.
