Why have seven prosecutors resigned from the Justice Department over the Eric Adams case?

Seven prosecutors resigned from the Justice Department because they refused to file a motion to dismiss criminal charges against New York City Mayor Eric Adams. They believed the dismissal motion was based on a lie, making this an unprecedented situation where multiple prosecutors took such a principled stand. The Acting U.S. attorney for the Southern District of New York sent a resignation letter to the acting deputy attorney general, who was previously one of Donald Trump's criminal defense lawyers. This unusual circumstance has transformed what would typically be a pro forma hearing into a significant judicial challenge, as Federal Judge Dale E. Ho will now consider the controversial dismissal motion knowing about these extraordinary resignations.
