A top lawyer for the Justice Department’s civil rights division wants Florida officials to explain why they’ve unilaterally decided to purge the state’s voter rolls of non-U.S. citizens just months before a key primary in the 2012 elections — an apparent violation of provisions in the landmark Voting Rights Act. In a two-page letter, T. Christian Herren, chief lawyer for Justice’s Voting Rights division, told Florida’s secretary of state that officials’ decision to comb the rolls for foreign nationals was launched without consulting Attorney General Eric Holder or asking permission from a federal court, long-standing requirements under Section 5 of the Voting Rights Act. Further, Herren writes, the state hasn’t officially justified why it launched the scrub, which activists say is haphazard, subjective and disproportionately hurts minority voters. At the same time, the practice is happening less than 90 days before an upcoming statewide election, which “appears to violate the National Voter Registration Act,” Herren said. “Please advise whether the state intends to cease the practice … so the [Justice Department] can determine what further action, if any, is necessary.”
