“Intercept” co-founder Glenn Greenwald said that MSNBC deliberately lied to its viewers about the credibility of the charges that the Trump campaign colluded with Russians to influence the 2016 election, claiming he and other left-wing journalists were banned from appearing on MSNBC due to their skepticism on the issue.

Talking to Fox News’ Tucker Carlson, Greenwald said that MSNBC “should have their top host on primetime go before the cameras and hang their head in shame and apologize for lying to people for three straight years, exploiting their fears to great profit. These are people who were on the verge of losing their jobs. The whole network was about to collapse. This whole scam saved them. Not only did they constantly feed people for three straight years total disinformation, they did it on purpose.”

Greenwald explained that “There was a whole slew, not just me, of left-wing journalists with very high journalistic credentials, far more than anyone on that network, like Matt Taibbi and Jeremy Scahill and many others… who were banned from the network because they wanted their audience not to know that anybody was questioning or expressing skepticism about the lies and the scam they were selling because it was so profitable.”

He contrasted that with Carlson, who even as a staunch critic of the investigation into collusion, had on his show Democratic Rep. Adam Schiff to explain his opposing point of view on the issue.

National Review said MSNBC did not immediately respond to a request for comment.
