Hillary Rodham Clinton, D-N.Y., on a tour of the site of the World Trade Center disaster, Sept. 12, 2001. Giuliani, once warmly regarded as "America's Mayor" in the wake of the 9/11 attacks, and who first rose to prominence as a federal prosecutor going after mobsters with a then-novel approach to racketeering cases, has seen his reputation tumble and his liberty threatened in defense of Donald Trump's bogus election fraud claims.
