Habba represented Trump in a legal case where he was being investigated for falsely representing the value of his assets on his New York State income tax returns. She attempted to appeal a court order requiring Trump and his children to give sworn testimony about the valuations they signed for when filing those returns, but her appeals were unsuccessful. New York's Attorney General, Letitia James, personally questioned Trump on August 10, 2022. Habba was present during the deposition and led the defense. Trump refused to answer any questions during the four-hour deposition by citing the United States Constitution's Fifth Amendment over 450 times.
