Hope its nothing too major for anyone involved
After Peyton, the Haslems are the most notable figures that graduated from UT and are the most important people at UT outside the students/teachers themselves. It would be a huge blow to the psyche of the university if something they were involved with was bad, especially since Bill is now governor.
Now like I said, it's all speculation. But when you got the FBI, the IRS, and the US Treasury department there......yikes that doesn't look good.
