A Manhattan grand jury has convened to hear evidence surrounding potential corruption involving Ingrid Lewis-Martin, a longtime senior adviser to New York City Mayor Eric Adams.

Lewis-Martin submitted her resignation on Sunday, marking a dramatic end to her tenure at City Hall.

A source familiar with the investigation confirmed the grand jury’s involvement just hours after news broke of her sudden departure. This development comes amid a broader federal probe into Mayor Adams’ administration.

Lewis-Martin’s resignation follows a turbulent period. In September, federal authorities seized her phones and searched her home shortly after she returned from a trip to Japan. Her exit also came a few months after Mayor Adams himself faced an indictment on bribery and conspiracy charges.

Despite the mounting scrutiny, Lewis-Martin has not been charged in any ongoing city or federal investigations. The unfolding case adds another layer to the challenges faced by the Adams administration as City Hall navigates an intensifying corruption probe.
