They only make themselves look petty, dictatorial, bought and sold to outright tyrannical doing this. Oh and they feed into the MSM propaganda narrative when they do this.
LA LA LA LA LA I CANNOT HEAR YOU LA LA LA LA LA
Thats certainly true from our perspective, but they are deliberately trying to deceive the leftwing viewers they do have to gin up even more hysteria about Trump. It becomes harder for lefties to push lies about Trump if they ever see for themselves what he actually says in total and in context without the partisan, misleading media spin.
Once people see that for themselves, then it becomes obvious that CNN and MSNBC are lying to them. The propaganda networks cant allow that to happen, so they are starting to blackout Trump, like they did during part of the general election campaign.
Im surprised they didnt realize earlier how much they are undermining their own propaganda by showing Trump.
