WASHINGTON (CNN) - Former New York City Mayor Rudy Giuliani said Thursday he made a "mistake" in not thoroughly vetting former New York City Police Commissioner Bernie Kerik.
But the Republican presidential frontrunner argued voters should instead focus on his entire mayoral record when evaluating his candidacy.
"I think voters should look at it, and what they should say is in that particular case I made a mistake," Giuliani said during a press conferred in Dubuque, Iowa. "I made a mistake in not clearing him effectively enough, and I take the responsibility for that"
"But when you balance that mistake against all the successes that we had and the reality that you make some mistakes and you make some correct decisions, I think the overwhelming record is a record of great success," the New York Republican added..
Giuliani's comments come the same day federal prosecutors are expected to indict Kerik on charges of tax fraud, corruption, and conspiracy counts.
