Federal agents have reportedly executed a second search warrant at the headquarters of Pilot Flying J, the company owned by Cleveland Browns owner Jimmy Haslam, according to the Cleveland Plain Dealer. The website knoxnews.com reported early this afternoon that "U.S. Attorney Bill Killian wouldn’t give specifics today or say where the warrant was served," but that the investigation was "ongoing." On Monday, federal agents descended on the Haslam family business in Knoxville in a raid the FBI described as part of an "ongoing investigation." The headquarters of Pilot Flying J, a nationwide chain of truck stops and convenience stores, was locked down for much of the day. In a statement released this afternoon, Pilot Flying J said several subpoenas also were served, though it did not disclose with whom the documents were filed. "It's not our place to be more specific,'' the release said. The release said the investigation appears "to revolve around the application of rebates to a small group of Pilot Flying J trucking company customers.'' The statement does not go into greater detail. The release said the company is cooperating with authorities, and it is conducting its own investigation. Source: The Redzone
