Maybe they drew straws. CBS pretends to report on Benghazi and NBC pretends to report on Obamacare, and then they both ignore each others reports. If we know anything we know the old media is in cahoots with the administration. They don’t do anything that violates their marching orders.
I'll bet that's exactly what they did. That way, they can provide the absolute minimum coverage of a story, while still claiming to have covered it.
