Police at the University of North Texas are investigating after after a social media post showed a student urinating on a Beto O’Rourke shirt before passing it on to one of his supporters.

The student in the video is a supporter of Donald Trump and can be seen wearing a “Make America Great Again” hat. Posted on Wednesday morning by on Twitter, the video was originally recorded via Snapchat.

The video begins with the student making vomiting gestures with his hand and mouth as he mocks a get-out-the-vote rally for the former Democratic Senate candidate as his fellow students chant, “It’s time to vote.” the video is captioned, “by far the grossest thing i’ve yet to see on this campus.”

The video then cuts to the student filming himself urinating on an O’Rourke campaign t-shirt while holding it over what looks to be a public or dorm room toilet. Other students can be heard laughing in the background. After that, the t-shirt is dropped into the same toilet.

Finally, the video ends with the student walking up to a group of O’Rourke supporters from the rally and offering the shirt. “Do any of y’all want a free Beto shirt?” he asks. “It got soaked, but if one of ya’ll want it?”

A female student grabs the shirt from the student. As the student walks away, he says, “Here you go. Thank you.”

Outrage quickly followed on social media with several people calling for the student’s arrest.

This is DISGUSTING! I hope the girls involved are notified about him and he gets reprimanded publicly for his actions. Neal do something ???? @UNTPrez
