Browns owner Jimmy Haslam says he's "very optimistic" about the outcome of a federal investigation involving his family's truck-stop chain.

Speaking to reporters as the Browns opened training camp, Haslam said he has been in "constant contact" with the NFL since the fraud probe began in April at his Flying Pilot J business. Haslam said the league has been supportive during the investigation.

Haslam recently reached a settlement to reimburse customers who were cheated out of fuel rebates. Haslam said the investigation has not been a distraction in rebuilding the Browns and he denied there were any problems with his cash flow, citing a recent renovation of the team's headquarters and plans to renovate FirstEnergy Stadium.

Haslam said he's excited about the upcoming season, but cautioned Cleveland fans to be patient.
