U.S. Rep. Sean Patrick Maloney won the Democratic nomination in New York’s new 17th Congressional District, comfortably holding back a challenge from state Sen. Alessandra Biaggi, according to The Associated Press.

"I'm proud of what we built together," Maloney told supporters in his victory speech Tuesday night.

Maloney, the chair of the Democratic Congressional Campaign Committee, defeated the vocal progressive state lawmaker, according to the latest unofficial results as of Tuesday night.

Biaggi was recently endorsed by U.S. Rep. Alexandria Ocasio-Cortez, while Maloney received the endorsement of former President Bill Clinton.

Maloney reached out to Biaggi supporters on Tuesday night.

"Our differences are far smaller than a primary campaign would have you believe," Maloney told the crowd. "Only together can we win the fight."

Maloney has represented the 18th District since 2013, but after the redistricting process this spring, opted to run in the 17th, which angered some officials in his own party, including Biaggi.

A former aide to Clinton, Maloney serves on the House Intelligence Committee. He will face Mike Lawler, who won a five-way Republican contest on Tuesday, in November.

The 17th District includes parts of Westchester, Putnam, Dutchess and Rockland counties.
