Democrats won two contested races for district attorney in the New York metropolitan area Tuesday, with incumbent Madeline Singas winning a second term in Nassau County and Melinda Katz taking over an open seat in Queens County.

Singas, a career prosecutor, was the county's acting district attorney before she was elected to the office in 2015. She previously led the special victims bureau in the DA's office.

She prioritized fighting the opioid crisis through treatment and focused on gang violence in her first term, and she has said the state's landmark crime reform bill, which will take effect in 2020, may have been written too quickly.
