“You want to make sure you do a thorough job,” he said, declining to go into specifics. “Obviously the FBI is looking at evidence, and if and when they reach a decision they’ll bring that information to our office.”

The FBI has subpoenaed information on Price’s real estate and automobile transactions, as well as records from his annual Kwaanzafest festival.

“Obviously, obviously, and part of the reason we don’t comment is that this is just an investigation,” Jacks said.
