A CONFRONTATION over a Donald Trump sticker on a US university campus erupted after a student threatened to smash a classmate’s computer over her allegiance to The Donald.

A physical fightbroke out on the Queens campus of St John’s University yesterday after the student posted a photo to Twitter of a woman with a “Trump Make America Great Again” sticker on her laptop and asked his followers to share the image.

“7000 retweets and i’ll smash this b---h’s computer,” the student wrote in the post, which ended up being almost 16,000 times.

The Trump supporter in the picture complained to the school’s public safety office, according to another student, the New York Daily News reported.

A short time later the two ran into one another in a hallway and a fight broke out over the tweet, students told the paper..

The tweeter, who uses the name OCK PAPI on the site, then punched the woman in the chest, one student alleged.

Friends reported that the woman tossed a cup of coffee at him during the heated exchange.

It was unclear if there were any injuries related to the confrontation.

“It was just a Trump sticker,” the sophomore said.

St John’s representatives did not immediately respond to a request for comment, but the school did post a statement on Twitter.

It is understood assault charges against the student, whose Twitter account has since been suspended, may be pursued.
