A viral video appears to show a man throwing a drink in the face of a teenager and stealing his "Make America Great Again" hat.

In the video, said to be filmed at a Whataburger around 2 a.m. on Wednesday, the man tells a group of teens, "You ain't supporting s---," before walking away with the hat.

The video has sparked outrage online, with people on the right calling for the man to be identified and arrested.

A viral video appears to show a man taking a teenager's "Make America Great Again" hat and throwing a drink at a Whataburger in San Antonio, Texas.

"So went out for a 2am snack and my friend (wearing a MAGA hat) had his hat stolen and a drink thrown in his face (and mine, you can see my arms on the left of the video)," the Twitter account @brxpug posted early Wednesday.

The video, which has been viewed more than 2 million times, shows a man throwing a drink and then walking away from the group at the table while holding a "Make America Great Again" hat.

"You ain't supporting s---," the man says.

A 16-year-old named Hunter Richard told the local news station WOAI-TV that he was the teen who had his hat stolen. WOAI reported that police were investigating the incident.

"I support my president, and if you don't, let's have a conversation about it instead of ripping my hat off," Richard told WOAI-TV. "I just think a conversation about politics is more productive for the entire whole rather than taking my hat and yelling subjective words to me."

A woman who is thought to be the mother of one of the teens in the video posted it on Facebook and asked people to help her identify the "scumbag of the year," The Independent reported. That post has since been made private or deleted, the report said.

The incident has sparked outrage online.

"We were shocked to see this video and certainly don’t condone this type of customer behavior in our restaurants," Whataburger said in a statement. "To be clear, no Whataburger employees were involved or witnessed the incident, and we ask that questions be directed to San Antonio PD as we continue supporting their efforts."

This is not the first time that supporters of President Donald Trump have said they were harassed for wearing the "MAGA" hats and other Trump gear.

In May, a 22-year-old said he was harassed and threatened by employees at a Cheesecake Factory in Miami, Florida, for wearing the "MAGA" hat. And in 2016, a group was turned away from a Cook Out in Colonial Heights, Virginia, when they showed up in Trump shirts and hats.
