There is considerable speculation that Orange Mayor Mims Hackett will plead guilty to federal and state corruption charges on Tuesday. U.S. Attorney Christopher Christie has scheduled a news conference for tomorrow, and Hackett is expected to appear before Federal Judge Jose Linares at 8:00 AM, and then before Superior Court Judge Betty Lester at 1:30 PM. Under that scenario, City Council President Lisa Perkins will become Acting Mayor until July 1, when Mayor-elect Eldridge Hawkins, Jr. takes office.
