Giuliani is not formally accused of wrongdoing, but the move by federal prosecutors in Manhattan indicates a new degree of legal peril for him. Prosecutors have a high bar for going after an attorney, whose communications with clients are typically protected from law enforcement, and must make a convincing case to a judge given a search may result in the disclosure of attorney-client communications to investigators. In 2018, the same office raided the apartment of Michael Cohen, Trump’s former attorney, later convicting him of a variety of charges.
