The U.S. Department of Justice’s Civil Rights Division deployed more than 500 staffers to polling places in 28 states—including New York, New Jersey, Pennsylvania and Connecticut—on Tuesday to ensure compliance with federal voting rights laws.

Division staffers have been sent to Brooklyn, Queens and Orange County in New York, to Middlesex County in New Jersey, to Philadelphia and Allegheny and Lehigh counties in Pennsylvania, and to East Hartford, Farmington, Hartford, Middletown, New Britain, Newington and West Hartford in Connecticut, among 67 jurisdictions, the DOJ said in a statement.
