Giuliani's financial woes could compound as he faces mounting legal exposure

His image as "America's mayor" in the wake of the 9/11 terror attacks made him an immediate contender for the Republican presidential nomination. And in the half-decade since he left New York's City Hall, lucrative consulting work and speaking fees had boosted his net worth to between $18 and $70 million, according to financial disclosures he filed at the time.

But Giuliani's presidential ambitions fizzled almost immediately, and the former New York City mayor failed to make it though Super Tuesday. It was a humbling political tumble -- and now, some 15 years later, his wallet appears to have taken an equally humbling hit.
