ALLENTOWN, Pa. (AP) — Delta Air Lines is apologizing for not removing a passenger who rudely professed his support for President-elect Donald Trump and insulted those who didn’t aboard a flight to Pennsylvania.

The (Allentown) Morning Call first reported that 21-year-old Emma Baum, who lives in Belize, posted a 45-second video of the man on Facebook. She was on the Delta flight from Atlanta to Allentown on Tuesday when she shot the video.

In it, the man shouted his support for Trump and said to those who didn’t, “We got some Hillary (expletives) on here?” and told others, “If you don’t like it, too bad” referring to Trump’s victory.

Delta says it is investigating the incident and is “sorry this disruption happened” and saying Delta is responsible for “ensuring all customers feel safe and comfortable.”
