In his most recent article, Greenwald correctly points out that if whistle-blowers do what these intelligence leaker did, Obama puts them in jail. He also points out that columnists at the NYT and Washington Post make careers out of repeating CIA and FBI anonymous sources without doing any journalistic investigation.
Everyone should put their critical thinking hats on and understand there is a large percentage of Washington DC that does not want renewed relations with Russia. It flies in the face of the cold war they never stopped fighting and American hegemony abroad.
Greenwald already did his investigation on the evidence of Russian involvement still being peddled by the media back in January, when the sad excuse for an intelligence report came out.
Similarly reading actual journalism gives you the keen eye to smell bullshit.
