Former New York City Mayor and onetime Republican presidential candidate Rudy GiulianiRudy GiulianiJake Tapper jokes he's retained Giuliani to look into fraud in 'Sexiest Man' election Pioneering New York City Mayor David Dinkins dies at 93 Trump transition order follows chorus of GOP criticism MORE predicted Friday that Treasury Secretary Tim Geithner will resign in time.

"I think he will [resign]," Giuliani said on Sean Hannity's TV show last night. "I think it's a matter of time, and how they finesse it, and how they explain it, and how they move on."

"There's a sense that either nobody's in charge, or if they are in charge, they don't know what the right hand's doing, what the left hand's doing," Giuliani added. "At a time like this, you can't have a Secretary of the Treasury that is someone people don't have confidence in."

Giuliani blasted Geithner and Senate Banking Committee Chairman Chris Dodd (D-Conn.) for a loophole in the stimulus package allowing for the payment of controversial bonuses to AIG executives, which roiled Washington this week.

"This is not just a question of negligence -- this was presented to them, they did agree to it," Giuliani alleged. "And now, all of a sudden, when the thing becomes a big disaster, they're all trying to run for cover."
