How are you a journalist and let that slip by unchallenged? Is he even listening?
He does that a lot. I think it's because he is often just waiting for his chance to talk again.
And I don't think he does much research before interviews either.

But on Kellyanne. She wouldn't go up there and just try to manufacture a massacre. She knows that is too obvious.
I think her talking points for the day had the massacres in the US and in Europe, and a mention of the Bowling Green terrorists because people are mentioning that no attacks happened from those 7 countries.
She just got her references mixed up.
