Where did you get this from? OC's statement mentioned raising money for local charities to get invited on the trip, but everything else is from Iowa's end. A few others have mentioned, but phrasing will be important.
If OC claimed to be an organization raising money or volunteering time for Boys and Girls club, then what they said isn't exactly a lie. It would still be sad an organization is willing to sink like $8,000 into a trip with only $2,000 going to charity and call it "charitable". Ultimately, that's on Iowa for failing to vet better.
If OC claimed the tickets were for boys and Girls Club then OC is in the wrong, and they deserve to take th financial hit.
At the end of the day, I feel there a lot of better ways Iowa could have handled this than dealing with the 3 days before a game and generating a wholly unnecessary PR story. It seems like Barta gets a hard on for trying to embarrass other schools, at times without fully vetting things. One that quickly comes to mind was the whole accusing Iowa State stealing from visitor locker rooms thing that was ultimately untrue.
