What led to the resignation of Danielle Sassoon as Acting U.S. Attorney for the Southern District of New York?

Danielle Sassoon resigned after refusing to comply with a direct instruction from the Justice Department to dismiss the case against New York City Mayor Eric Adams. Deputy Attorney General Emil Bovet accepted her resignation in an eight-page letter, stating that her decision was based on continuing to pursue what he described as a 'politically motivated prosecution' despite explicit instructions to drop it. The letter criticized Sassoon for losing sight of her oath to the Department of Justice by suggesting she retained discretion to interpret the Constitution contrary to department directives. As a result of this conflict, Sassoon's resignation was accepted, though Mayor Adams' case technically remains active and has not been officially dropped.
