CNN and the other msm consider themselves a branch of the government, and the preeminent branch, to boot. They are showing their tyranny by blackmailing a free citizen into retracting his free speech, which not even a legitimate branch of government has done (Kathy Griffith and all the other leftists who have made either implied or open threats against President Trump and covered themselves with the First Amendment). CNN is accruing powers to itself that not even the government (at least not the Trump administration) claims.
Seriously, President Trump needs to bar CNN from press briefings for a time period to be determined. He needs to just tell them that he’s only following their playbook, and they have no more rights than the private citizen they threatened into retracting his free speech which was by no measure threatening.
CNN has no right to be present amongst legitimate (such as they are) news organisations. They are illegitimate.
