TRENTON - Trenton Mayor Tony Mack returned to work today following an FBI raid at his home two weeks ago. The mayor made his first public appearance since the raid at a local library's ribbon-cutting ceremony this afternoon. Renamed the East Trenton Learning Center, the facility has been closed to the public for two years. A search warrant revealed that agents were looking for evidence of bribery and money-laundering at Mack's residence. He went on a previously planned vacation after the raid. The mayor refused to comment on what the FBI requested, but has indicated his administration would be completely transparent. FBI seeking evidence in probe against Trenton mayor
