>Depends who he's talking about as being a chronic liar.
Actually, no. As the belief goes…
"The president of the United States cannot be a chronic liar."
The ambiguity arises such that POTUS cannot be a chronic liar. The words (attributed) to Comey are true, because POTUS isn't a chronic liar. Do you see? This is how I know that Comey didn't write this because the writes seems most intelligent.
