Rudy Giuliani sued by longtime former lawyer over alleged unpaid bills

A lawyer who for years represented Rudy Giuliani in a variety of legal matters sued him on Monday.

Robert Costello and his firm, Davidoff Hutcher & Citron LLP, allege in the suit that the former New York City mayor owes them nearly $1.4 million.

The lawsuit claims Costello and the firm represented Giuliani during criminal investigations by the U.S. Attorney for the Southern District of New York, the Fulton County District Attorney's Office, special counsel Jack Smith and during the U.S. House Jan. 6 committee's investigation.
