well as CNN's, and I couldn't find a single mention of the 'CNN staffer's secretly recorded conversation' that the NY Post "reported" on...so I can't comment on a CNN 'confession' regarding some alleged 'propaganda'...looks like the Post has this "scoop" all to themselves.
Now, as to your contention that there was a whole lot of false propaganda against Donald Trump, I'll refer you back to that list of prominent Republicans who un-equivocally supported his removal from office...some of whom might have used their own version of "propaganda" to emphasize - much more directly than any CNN or other MSM outlet - their 'displeasure' with the man.
It seems to this observer that the constant use of terms like 'propaganda' or 'fake news' or 'enemy of the people' can actually be cases of "projection" to deflect from the real perpetrators...just saying.
