Where CNN is trying to sabotage Sanders would they do the same thing to Trump ?

It was inexcusable for CNN to leave that microphone live and dirty politics to release it publicly.

CNN has outright lied about the President for 3 years now.

they have a history, since they can get away with it, why stop now.

They have and do . Remember when they got debate questions to Hillary before the debate 

CNN is the media arm of the DNC.  Republicans have known this for years; Democrats might finally be waking up to that.

They don't like Sanders since he isn't bought by corporations. 

CNN has been trying to overthrow Trump since 2015. Bernie Sanders probably can not do it because there are not enough Socialists in America for him to win.
