Actually, the article said that they aren't even allowed to pay face value for the seats. It's because the Cubs were offering tickets to purchase at face value. Which is ridiculous. If it was about giving them tickets, then I could understand.
ETA: At the end of the article it says the politicians could get fined $1000-$5000 if found in violation. So, you pay $175 for two tickets, that's $350. Plus, let's go for the max fine of $5,000. That comes to $5,350. For two tickets. Which is probably cheaper than what the cost of two tickets on Stub Hub are going for. I say they should do it!
