The disciplinary office for D.C. lawyers brought ethics charges against Rudy Giuliani on Friday related to claims he made in a federal lawsuit in Pennsylvania that sought to overturn that state’s 2020 election results.

The District’s Board on Professional Responsibility alleged that Giuliani “brought a proceeding and asserted issues therein without a non-frivolous basis in law and fact for doing so” and “engaged in conduct prejudicial to the administration of justice,” two violations of the Pennsylvania rules of professional conduct.
