Other than being dumb enough to go to a strip club, I don't see the issue with it. Brennan obviously didn't know this Rossi guy was going to reneg on his money, and $23,000 spent on a trip courting a donor who pledged $3,000,000 seems like fairly smart money to me. If a prospective $3 million Iowa donor wants to go to Indy last minute and our AD buys club level tickets to get it done, I say swipe the card.
I'd bet the deed to my house this happens multiple times a year at every major sports program including Iowa. The difference is having guys smart enough to stay out of strip clubs and not impregnating beer cart girls at a golf tournaments in nebraska ***AHEM***
Much ado about nothing, no public money, and more than likely just a disgruntled employee. WGLT news didn't just find out about it by accident. Someone was pissed at this AD and fed the news station emails and the address of the strip club.
