Prosecutor Departures Highlight Tensions Within Nassau County DA Office

Since Anne Donnelly assumed leadership in 2022, approximately 90 prosecutors have left the Nassau County District Attorney’s Office, according to her political challenger, Nicole Aloise. Aloise, a Democrat running against Republican Donnelly, claims the office has become a toxic environment, prioritizing headlines over justice.

Appearing outside the Nassau courthouse, Aloise stated, “I believed I would serve here for life, but after Donnelly took over, the focus shifted from justice to her personal agenda.” She accused Donnelly of fostering a culture that hampers effective prosecution, citing her own departure in 2023 due to resource restrictions that prevented pursuing a major conspiracy case.

Supporters and former prosecutors shared concerns about declining collaboration, diminished support for long-term investigations, and a perceived shift towards politicization. One anonymous former employee remarked, “You can either treat prosecutors poorly or compensate them well — Donnelly did both.”

Supporters of Donnelly point to a reported 25% decline in major crimes early in 2025 and argue that long-term crime data, dating back to 2014 and 2016, show Nassau County remains one of the safest areas. Critics, including Aloise, suggest that spikes in crime during Donnelly’s tenure reflect deeper issues in leadership and priorities.

While some attribute recent crime trends to broader national policies, Aloise argues that internal management problems are undermining long-term prosecution success.
