Why won’t they? Exactly what do they have to lose?
If Benghazi blows sky high and they don’t at least “look” like they demanded answers.. they’ll get grouped in with the cover up. Something they DO NOT want.
They don’t care about Obama. He’ll be thrown under the bus quicker than you can say Watergate.
What's the saying, if you take on the king, you better kill him? I don;t think Kerry would throw Obama under the bus. It's easier to play dumb - or in Kerry's case, act natural.
They might make some noise, but they'll be satisfied with a BS answer from whoever it is they are purporting to grill.
