PLAINFIELD - Democratic Mayor Adrian Mapp has formally kicked off his campaign for a third term in office. His announcement came Thursday evening during a livestreamed virtual fundraiser featuring Gov. Phil Murphy and U.S. Sens. Bob Menendez and Cory Booker, who endorsed Mapp's reelection. “I have been honored to serve the city of Plainfield as mayor for the past seven years. Together, we have helped to make our beautiful city a fairer, safer, and more prosperous place to live and raise families,” Mapp said. “In pursuing reelection, I intend to deepen our commitments to economic growth and development in a way that lifts all boats and helps our city build back better from the devastating COVID-19 pandemic.”
