Greenwald loves to praise himself for vetting stuff instead of dumping documents. Meanwhile he essentially sold out to a rich guy and has barely released any docs since the original stuff. In addition, in this interview, he couched everything about Hillary within "Trump is (bad thing) but...". I think there's a very good chance he's controlled opposition.
Greenwald gets lambasted by the left everyday as a trump supporter because he is often pointing out how bad HRC is. He couched his statements to avoid the HRC trolls. I bet it still wasn't good enough for them.
I often like much of what Greenwald says, but it's sad that the Clinton campaign is considered conventional and Trump's not. The amount of corruption surrounding Clinton is staggering and apparently that's simply "conventional" or normal these days.
