Giuliani, Once 'America's Mayor,' Now a Central Figure in Trump Impeachment Inquiry Rob Garver WASHINGTON - It's been a long, strange road for Rudy Giuliani, the hard-nosed prosecutor who gained fame as "America's Mayor" for his leadership in New York City after the terror attacks on September 11, 2001. Once seen as a promising Republican presidential candidate himself, Giuliani is now trying to beat back accusations that he was a key player in an international scandal that has President Donald Trump facing an impeachment inquiry. Over the course of the past two years, Giuliani, 75, has held multiple meetings with officials from Ukraine as part of an effort to persuade that country's government to open an investigation focused on former Vice President Joe Biden and his son, Hunter Biden, who served on the board of a Ukrainian energy company called Burisma Holdings. At the same time, Giuliani was pushing for a separate investigation into alleged cooperation between Ukrainian officials and Hillary Clinton's campaign in the 2016 election, suggesting that Joe Biden had also played a role in that unproven conspiracy. .
