FILE -- This March 27, 2013, file photo shows Tennessee Gov. Bill Haslam during a news conference in Nashville, Tenn. Haslam has struggled almost from the start of his administration to fulfill a campaign pledge to avoid handling matters relating to Pilot Flying J, the truck stop chain his family owns. Now, an FBI investigation of alleged fraud by the sales staff at the nation's largest diesel retailer has brought increased scrutiny and raised more questions about links between the governor and Pilot.(AP Photo/Mark Humphrey, File)
