It is still on his desk. Typically once a bill is transmitted to his desk, the Governor has ten days to make a decision, but from what I understand he only had until today to make a decision on this legislation. I assume this is because the general session has officially adjourned. Haslam left for Asia this morning on a trip to pull in business from Asia to Tennessee, so if he was going to veto it, he would have had to do that this morning. According to the TN State Constitution, if the legislation isn't signed, it simply becomes law without his signature.
It is important to remember though that this legislation ONLY allows permit holding full-time faculty members of state colleges and universities to conceal a handgun at the institution at which they are employed. If you are not a permit holding full-time faculty member, THIS CHANGES NOTHING FOR YOU!
