From personal history I know Faiz Shakir to be a controlled opposition asset of the Center for American Progress who believes strongly in the power of censorship. I also know from his history he is heavily involved with John Podesta (whom Shakir calls his "mentor") and the Clinton machine.
Why is Shakir now running Sanders' campaign? The obvious answer is... to exert centrist unDemocratic Party control over it and the messages it conveys during the campaign.
If you support Sanders' candidacy, you should demand Shakir be fired immediately.
