Mayor Tony Mack, 46, on Wednesday denied wrongdoing after the FBI spent the overnight hours searching his home, and the homes of his brother, Ralphiel Mack, and businessman Joseph Giorgianni, a campaign donor who is a convicted sex offender.

The Democratic mayor's first two years in office have been punctuated by accusations of reckless spending, cronyism and mismanagement.

Questions have also lingered about how Mack financed his 2010 campaign at a time of personal financial problems. His home and other properties have faced foreclosure, and last month properties belonging to him, his brother and Giorgianni were all reported by the city to be late on tax payments.

Mack has turned City Hall into a revolving door through a series of heavily criticized appointments.
