UNC-Chapel Hill has hired K&L Gates, a law firm with ties to Republican state legislators, to lead its investigation into the School of Civic Life and Leadership, people familiar with the probe said. People with knowledge of the investigation said that Nathan Huff, a partner in the firm’s Research Triangle and Charlotte offices, has been leading interviews as part of the review. Chancellor Lee Roberts revealed the investigation at a faculty meeting last month after a year of conflict, resignations, and a firing. He also represented Berger and Moore when they sued the U.S. Department of Health and Human Services to prevent Gov. Huff has also represented UNC-CH and East Carolina University’s health systems in 10 lawsuits against health insurance companies.
