New York Gov. Eliot Spitzer has admitted involvement in a prostitution ring, The New York Times reports.
"To say this is a shock is an understatement," said CNN senior legal analyst Jeffrey Toobin, who went to law school with Spitzer.
Spitzer served as New York's attorney general for eight years before being elected governor.
Time magazine named him "Crusader of the Year" during his two terms as New York attorney general.
Tabloids labeled him "Eliot Ness," after the hero in the crime drama "The Untouchables," because of his reputation for rooting out corruption, busting white-collar criminals and tackling organized crime.
He was also known for prosecuting several prostitution rings.
He also worked as an assistant district attorney in Manhattan and worked for three New York law firms after receiving his law degree from Harvard.
The first-term Democrat had been considered a rising star among his party.
Spitzer is married and has three daughters.
