New York State Sen. Alessandra Biaggi is throwing her support behind insurgent Westchester district attorney candidate Mimi Rocah.

Biaggi will announce Tuesday that she’s endorsing Rocah, the former federal prosecutor and MSNBC legal analyst who is looking to unseat incumbent Anthony Scarpino in a Democratic Party primary.

“Mimi will be a powerful voice for democratic justice and all victims across Westchester County — in the face of unprecedented federal policies that are having a direct effect on the state and local level today,” Biaggi said in a statement.

ANNOUNCEMENT: Rocah to challenge Scarpino for DA

Biaggi won her seat in the state Senate’s 34th District in 2018 as an insurgent primary challenger facing a well-funded entrenched incumbent, Jeff Klein, the former leader of a faction of Democrats that sided for a time with Republicans called the Independent Democratic Conference.

Rocah said Biaggi stood up to “machine politics” in her own victory.

“She fought for a more diverse, inclusive representation for New York and won,” Rocah said in a statement. “Sen. Biaggi represents the incredible power that progressive women leaders have, and I look forward to carrying on that legacy as District Attorney.”

Rocah, a 49-year-old Scarsdale resident, is looking to gain traction against Scarpino who is seeking his second four-year term this year. Scarpino, 68, of Bedford became DA after spending time as a state Supreme Court Justice and Westchester surrogate judge.

The candidate raised more than $325,000 in roughly a month after launching her campaign in December and picked up a high-profile endorsement from Preet Bharara, former U.S. attorney for the Southern District of New York. Scarpino has raised $300,000 since his last election and $129,000 since the last cycle ended in July. His first large fundraiser of this election cycle was scheduled for Tuesday.
