The FBI is investigating the unsuccessful Florida congressional primary campaign of an unknown Democratic candidate who may have improperly received thousands of dollars for mail services from Republican U.S. Rep. David Rivera.
A senior law enforcement official, speaking on condition of anonymity because the probe is ongoing, confirmed Thursday to The Associated Press that investigators are looking into direct-mail and voter data services used by Justin Lamar Sternad's campaign prior to the Aug. 14 primary.
The investigation was first reported by The Miami Herald. The FBI declined to confirm or deny the probe.
At least one of Sternad's mailings was critical of the eventual Democratic nominee, Joe Garcia, who has previously tried to unseat Rivera. Sternad claims he loaned money to his campaign for the mailings. Rivera denies any connection.
