Jokers: Journalists David Cay Johnston and Wayne Barrett, the latter of whom wrote an unauthorized 1992 Trump biography, have claimed that Trump and his companies did business with New York and Philadelphia families linked to the Italian-American Mafia. A reporter for the Washington Post writes, "he was never accused of illegality, and observers of the time say that working with the mob-related figures and politicos came with the territory." Trump helped a financier for the Scarfo family get a casino license, and constructed a casino using firms controlled by Nicodemo Scarfo. Trump also bought real estate from Philadelphia crime family member Salvatore Testa, and bought concrete from companies associated with the Genovese crime family and the Gambino crime family. Trump Plaza paid a $450,000 fine leveled by the Casino Gaming Commission for giving $1.6 million in rare automobiles to Robert LiButti, the acquaintance of John Gotti already mentioned. Starting in 2003, the Trump Organization worked with Felix Sater, who had a 1998 racketeering conviction for a $40 million Mafia-linked stock fraud scheme, and who had then become an informant against the mafia. Trump's attorney has said that Sater worked with Trump scouting real estate opportunities, but was never formally employed.
