The Cheesecake Factory says it has suspended workers involved in an incident in which a black customer reportedly was subjected to verbal abuse by restaurant staff over his "Make America Great Again" cap.

Eugenior Joseph, 22, was dining with his girlfriend's family at a Cheesecake Factory restaurant in Miami on Sunday, when his red MAGA hat was spotted by a female staff member, according to the Daily Wire, which first reported the incident. After the woman encouraged her co-workers to confront Joseph, about a dozen Cheesecake employees surrounded his table, multiple witnesses told the conservative news site.

One employee tried to scare Joseph by standing behind him "balling his fists, smacking his fists," Joseph told the Daily Wire. When he exited a restaurant bathroom, Joseph encountered employees "clapping and yelling, and just screaming things at me," he told the site.
