Cizilla is obviously a liar with no basis in fact for his claims. Zero evidence exists that Trump has ever attempted to "undermine free and independent media," and moreover (if Cizilla was attempting to imply CNN as the entity that was somehow "undermined") the multibillion-dollar Time Warner subsidiary for which he works is the furthest possible from being "free and independent."
There are many other total falsehoods, logical fallacies and shallow, irrelevant remarks in corporate mass media employee Cillizza's editorial rant, most of which reads like a 'hurt feelings report'.
Trump's own rhetoric and topics covered are no different in tone or scope than what he's been saying in his largely SamIzDat campaign speeches from 2016; in fact compared to some of the October 2016 speeches such as the West Palm Beach http://portland.indymedia.org/en/2016/10/433420.shtml one <--- quoted ^^, during that specific time late in the campaign when the real possibility of losing to Clinton existed — amongst an avalanche of U.S. corporate mass media predictions of "80% landslide" and assured Clinton victory — and was anxiously reflected in Trump's comments and rhetoric, last night's Montana speech was tame and calm (perhaps even nuanced) in comparison.
In total, Chris Cillizza is pimping the same shopworn banner that he and other U.S. corporate mass media pundits have since the emergence of Trump and particularly since mid-2016, when it became apparent that he could actually win the GOP nomination (which the Republican National Committee with millions of dollars in support from top elites including private corporate donors and Democrats had attempted to sabotage and prevent). The October 2016 remarks by Trump in Florida are evidence of this longstanding feud, in addition to direct threats against the incoming president the following January by CNN President Jeff Zucker :
