Rudy Giuliani has turned to Jon Sale, a former prosecutor now practicing 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 ALM on Tuesday. Sale, who was law school classmates with Giuliani, was an assistant special Watergate prosecutor. He is of counsel at Nelson Mullins in Miami and co-chairs the firm’s white-collar and government investigations practice group.
