Dwayne Dixon, a professor at the University of North Carolina at Chapel Hill, was reinstated Friday after the university performed a “thorough threat assessment,” Dean Stoyer, vice chancellor for communications and marketing, said in a statement. 

Dixon was placed on leave Monday following allegations that he was an advocate for political violence.

“The Carolina Behavioral Threat Assessment and Management Team consulted with the UNC System security office and with local law enforcement, undertaking a robust, swift and efficient review of all the evidence. We have found no basis to conclude that he poses a threat to University students, staff, and faculty, or has engaged in conduct that violates University policy,” Stoyer said in a statement. “As a result, the University is reinstating Professor Dixon to his faculty responsibilities, effective immediately.”

Dixon is a teaching associate professor of Asian and Middle Eastern studies at UNC Chapel Hill, and he’s been active at counterprotests to alt-right rallies, including at the Unite the Right rally in Charlottesville, Va., in 2017. He’s also a strong advocate for gun rights and used to be a member of the Silver Spring Redneck Revolt, a chapter of the now-disbanded antifascist, antiracist, anticapitalist political group Redneck Revolt. Andrew Kolvet, a spokesperson for the late Charlie Kirk’s Turning Point USA, called for Dixon to be fired in an X post because of these affiliations.
