Rudy Giuliani, a Republican who served as New York city’s mayor from 1994 until 2001, was widely praised for his leadership in the aftermath of the Sept. 11 attacks and earned the nickname “America’s Mayor.”
Before he became mayor, Giuliani served as the associate U.S. attorney general from 1981 to 1983 and as the U.S. attorney for the Southern District of New York from 1983 to 1989. He helped lead the federal prosecution of several New York City mafia bosses, famously targeting then-Gambino crime family leader John Gotti and others by using the Racketeer Influenced and Corrupt Organizations Act.
