Federal prosecutor leads corruption investigations potentially implicating administration
Nadia Shihata, a federal prosecutor who led the high-profile R. Kelly case, becomes nominated as Department of Investigation commissioner under Mamdani. The appointment, announced February 12, 2026, requires City Council confirmation. Shihata will oversee corruption investigations across city governmentinvestigations that could eventually implicate the administration itself.
Federal Prosecution Background
Shihata’s most high-profile prosecution work involved the R. Kelly music industry sexual assault case, which received significant media attention and resulted in major convictions. Her background in federal law enforcement and complex criminal prosecution positions her for the DOI role. The appointment signals Mamdani’s intention to project serious anti-corruption commitment.
Department of Investigation Mandate
The DOI investigates corruption and wrongdoing within city government, including city employees, contractors, and officials. Investigations can lead to employee discipline, referrals for prosecution, and internal policy reforms. The office has authority to investigate city agencies and, potentially, the mayor’s own administration.
Independence and Political Pressure
The relationship between the mayor and the DOI commissioner is inherently delicate. The mayor appoints the commissioner but the commissioner’s investigations may create problems for the mayor. Previous commissioners have faced pressure to slow investigations into mayoral allies or allies’ concerns. Shihata’s background and Mamdani’s public commitment to anti-corruption will be tested when investigations involve political allies.
Contractor Fraud and Accountability
The DOI investigates fraud involving city contractors. Given the city’s large purchasing power, contractor oversight matters significantly. Shihata will oversee investigation of contractor fraud, kickback schemes, and bid-rigging. This work has implications for housing development, infrastructure projects, and city service contracts.
Oversight and Agency Relations
The DOI must cooperate with other city agencies, the NYPD, and federal authorities on investigations. Shihata will manage these relationships and determine investigation priorities and resources.
