Rudy Giuliani turned to Miami attorney Jon Sale, a former federal prosecutor now at Nelson Mullins Riley & Scarborough, to represent him in the budding congressional impeachment investigation into President Donald Trump and his foreign affairs.

Sale confirmed his representation of Giuliani, the president’s personal lawyer, to several media outlets Tuesday. Sale, who was a New York University law school classmate of Giuliani, was an assistant special Watergate prosecutor. He is of counsel at Nelson Mullins and co-chairs its white-collar and government investigations practice.
