BS. Hewitt was not asking about obscure terrorists unknown to anyone but the intelligence community. He specifically asked about the heads of the biggest terrorist organizations out there - Hezbollah, al Queda, ISIS, etc. Maybe the average LIV would not know who these people are, but someone wanting to be president SHOULD - these groups are threats to the US.
So... do you think any of the other candidates KNOWS the names of all the terrorist leaders ?
