(Providence, RI) -- Round two of debates between candidates for Rhode Island governor took place on Monday night. Democratic incumbent Gina Raimondo, Republican challenger Allan Fung, independent candidate Joe Trillo and Moderate Party candidate William Gilbert all took the stage at the University of Rhode Island for a debate sponsored by the university, The Providence Journal and The Public's Radio. On the topic of immigration, Cranston mayor Fung pointed to his recent agreement to have his city's police cooperate with federal immigration enforcement efforts, Trillo said have state police cooperate more in the same manner, and Raimondo criticized both for trying to politicize an issue of public safety. Trillo also faced questions about his past, including a reported altercation in 1975 with now-House Speaker Nicholas Mattiello, and also a group of Black Lives Matter protesters which got on his case for alleged use of a racial epithet during the 1975 incident. Trillo denies that he used a slur.
