The FBI says it searched two other homes during a middle-of-the-night raid of the house of Trenton, N.J., Mayor Tony Mack.

Tax records show the properties belong to Ralphiel Mack, the mayor's brother, and to Joseph Giorgianni, a convicted sex offender who donated to Tony Mack's run for mayor.

Federal authorities will not say what they are investigating.

The mayor says he has not violated the public trust but declined further comment.

Telephone messages seeking comment from his brother, a high school football coach in Trenton, and from Giorgianni were not returned.

Mack's two-year administration of New Jersey's impoverished capital city has been marked by accusations of cronyism and reckless spending. Questions have also lingered about the financing of his campaign at a time of personal financial problems.
