TRENTON, N.J. (AP) — U.S. Rep. Donald Payne Jr., a New Jersey Democrat and a member of the Congressional Black Caucus who replaced his father in the seat, died Wednesday after a heart attack this month that left him hospitalized, officials said. He was 65.

Gov. Phil Murphy called his fellow Democrat a “steadfast champion for the people of New Jersey” in a statement confirming Payne’s death.

Payne served for 12 years in the Newark-area seat his father had held for more than two decades. Representing a heavily Democratic and majority Black district, Payne drew strong marks from liberal organizations for his voting record.

“With his signature bowtie, big heart, and tenacious spirit, Donald embodied the very best of public service,” Murphy said. “As a former union worker and toll collector, he deeply understood the struggles our working families face, and he fought valiantly to serve their needs, every single day.”
