"There were mistakes made with Bernie Kerik," Giuliani said in an interview with the Associated Press while in New Hampshire. "But what's the ultimate result for the people of New York City? The ultimate result for the people of New York City was a 74 percent reduction in shootings, a 60 percent reduction in crime, a correction program that went from being one of the worst in the country to one that was on '60 Minutes' as one of the best in the country, 90 percent reduction of violence in the jails."
Giuliani was a staunch supporter of Kerik's nomination by President Bush to head the Homeland Security Department. That nomination fell apart amid allegations that Kerik, while corrections commissioner, paid less than $18,000 to a contractor for nearly $200,000 worth of renovations to his apartment. In 2006, Kerik pleaded guilty to misdemeanor charges related to the renovation.
"It was a mistake not checking him out as thoroughly as I should have," Giuliani told the AP about the failed nomination.
Longtime Kerik attorney Joseph Tacopina declined to comment.
Kerik's tax attorney, Ken Breen, was not immediately available for comment, his office said.
The U.S. Attorney's Office for the Southern District of New York said it does not confirm or deny the existence of the investigations.
