The U.S. Department of Justice is demanding that Hillsborough turn over voter-purge records, pulling the county into a growing legal fracas over Gov. Rick Scott’s push to clean out the state’s voter registry. The county received a subpoena Wednesday for documents dating to Jan. 1 relating to any efforts at identifying voters as potential noncitizens. The subpoena stems from a lawsuit filed June 12 in Tallahassee by the federal government against Florida and Secretary of State Ken Detzner over state efforts to scrub voter rolls. Hillsborough Elections Supervisor Earl Lennard said he would comply with the subpoena. Like supervisors across the state, Lennard halted efforts to purge voters when the tools to cross-reference citizenship and voter registration — a Department of Homeland Security database and motor vehicle records — proved unreliable, he said.
