Three former employees of Cleveland Browns owner Jimmy Haslam's truck stop chain have pleaded guilty to federal charges involving a scheme to cheat trucking companies out of promised fuel rebates. The three are among 10 former Pilot Flying J employees to plead guilty since federal agents raided the company's Tennessee headquarters last year. All have agreed to cooperate with the government in exchange for a reduced sentence. Among the trio is Brian Mosher, a former director of sales, who admitted to training other employees on how to cheat customers.
