Jimmy Haslam, whose purchase of the Browns was unanimously approved in October, apologized to fellow NFL owners for the negative attention an ongoing federal investigation targeting his family business, Pilot Flying J, has brought upon the league, Jarrett Bell of USA Today reported.

Since the FBI and Internal Revenue Service raided the headquarters of Pilot Flying J April 15 in Knoxville, Tenn., Haslam has issued several apologies and denied his knowledge of an alleged fraud scheme the FBI says cheated trucking-company customers out of millions of dollars of rebates they were contractually promised for buying certain amounts of diesel fuel.

Haslam, the CEO of Pilot Flying J, continued to maintain his innocence while explaining his side of the story to his NFL brethren Tuesday during the league meetings in Boston, according to the report. He addressed the other owners for about five minutes before a lunch break. It wasn’t on the agenda, but Haslam asked NFL Commissioner Roger Goodell if he could speak to the group.

“I thought it was important,” Haslam told USA Today. “We’re partners in the NFL. I wanted to address them face-to-face.”

Haslam became a minority owner of the Pittsburgh Steelers in 2008 before striking a deal this past summer to buy the Browns from Randy Lerner for about $1 billion. Steelers President Art Rooney II told USA Today he “was shocked” when he first heard about the accusations against Pilot Flying J, which is owned by Haslam and his family.

“I felt like it’s nothing Jimmy would become involved in,” Rooney said. “I feel like I know Jimmy. … He’s not someone who’d be breaking the law.”

Haslam and Goodell met last month about the investigation, and NFL spokesman Greg Aiello said the league has no plans to ask Haslam to surrender operational control of the Browns during the probe. No charges have been filed in the case.
