Pelham native and two-term Democratic State Sen. Alessandra Biaggi announced Monday she is running for Congress in New York’s 3rd District, which was transformed in the new electoral map approved by the legislature from a Long Island and Queens constituency to one that also encompasses parts of the Bronx and the sound shore of Westchester County from Pelham to Port Chester.

The seat is currently held by Rep. Tom Suozzi (D-N.Y.), who is running against Democratic Gov. Kathy Hochul. He has represented the 3rd District since 2017.

Biaggi is entering a primary field crowded with five Long Island candidates, including Democratic National Committee member Robert Zimmerman of Great Neck, Nassau County Legislator Joshua Lafazan, Deputy Suffolk County Executive Jon Kaiman, business executive Reema Rasool of Oyster Bay and Melanie D’Arrigo, who lost a previous primary to Suozzi.

Biaggi has pushed a progressive agenda since upsetting incumbent Jeffrey Klein in a primary in 2018. Klein was head of the Independent Democratic Caucus, which voted with the Republicans in the state senate.

“Our country doesn’t just need more Democrats in Washington, we need bolder ones,” Biaggi said in a statement. “I am running for Congress in NY-3 to bring progressive and honest leadership to the frontlines of our country’s most important fights. Hard working families of Westchester, Long Island, the Bronx and Queens deserve an experienced, strong and fearless leader in Washington.”

“As the representative of the sound, I will work to combat climate change and protect our shorelines, expand voting rights, enact universal pre-K to support working parents, provide opportunity and relief for the middle class, protect abortion rights, ensure public safety and a fair criminal legal system and deliver affordable healthcare for all,” she said. “Together, we delivered progressive change on these issues in Albany, and it is time to bring our energy and resolve to Washington.”

The newly drawn 3rd District includes parts of Biaggi’s current state senate district in the Bronx and southern Westchester. In essence, it wraps around the Long Island Sound from Suffolk County to the Connecticut line. She is a fourth-generation resident of the district.

The new district map has been challenged by a group led by the Republican Party in State Supreme Court in Steuben County. Based on registrations, it made several districts easier for Democrats win.
