Trey Gowdy actually said...

You have already said multiple times today that there was no evidence that you found of any criminal wrongdoing.

When a party has a duty to preserve evidence or records and they fail to do so, there is a negative inference that is drawn.

So you don't have any idea whether there's any criminal conduct or not because you don't know the elements of the offense?

I'm just simply saying we will never know because you didn't keep the evidence.
