COTTON: Let's turn our attention to the underlying activity at issue here. Russia's hacking of those e-mails and the allegation of collusion. Do you think Donald Trump colluded with Russia?
COMEY: That's a question I don't think I should answer in an opening setting. As I said, when I left, we did not have an investigation focused on President Trump. But that's a question that will be answered by the investigation, I think.

Either Mr. Cotton knew Comey wouldn't say no (which leads to endless  speculation) or he's not real bright.
