WASHINGTON _ Rudy Giuliani once was known as "America's mayor," having led New York City and the country through the aftermath of the Sept. 11 terror attacks.
He now is better known as personal attorney to President Donald Trump. And he again has been thrust into the national spotlight, this time as a central player in the whistleblower saga engulfing the White House.
Giuliani, his contacts with Ukrainian officials on behalf of Trump and his retention of clients with foreign interests are what House Democrats see as key in their impeachment inquiry of Trump.
