United Airlines is investigating after one of its employees allegedly threatened to call ICE on a customer they accused of not being a U.S. citizen. The exchange allegedly took place at the ticket counter at San Francisco International Airport last week. Footage of the incident shows her saying “maybe we should call ICE on you,” before adding that “you don’t act like a citizen. “It’s intimidating, because my kids didn’t know, you know, if when we get back, are we, am I going to be arrested?” “Is ICE going to be there?”
