Phoenix police Sgt. Trent Crump said Horne is facing a class three misdemeanor charge for leaving the scene of the collision which happened in March 2012.

It may have been a minor fender bender, but it turned into a major headache for Horne.

According to court documents, Horne was driving a friend’s car when he got into the accident, striking a parked SUV. That accident put Horne’s relationship with a woman who works for him under the microscope.

On March 27, 2012 at 12:45 p.m., two FBI agents had Horne under surveillance.

The federal investigators were tailing Horne in the course of their investigation into allegations of campaign finance violations .

The agents watched Horne and his employee, Carmen Chenal, drive to 202 West Roosevelt, where Chenal has an apartment. They then saw Horne back into a vehicle, a white Range Rover, then drive off without leaving a note.
