Obama spent more than a million dollars of private money keeping his paper trail secret, so it's a cinch that he's put the full resources of the federal government toward that mission. There's no telling how many leaks and hacks the FBI, CIA, and NSA have thwarted. There's no telling how many potential informants have been bribed, threatened, or killed. Many of the media outlets that might publish damning information are leftist, so they'd spike it if it got loose. The rest are probably scared sh!tless. I doubt that Julian Assange or even Anonymous would risk a drone strike.
