What Wallace said to PDJT was that those who really do seek to suppress & control the press are using the same lines as PDJT is to discredit the media in their own countries.
To a large degree, that statement by Chris Wallace is correct. There are in fact leaders in other countries using the term "fake news" and discrediting the media in their own countries as a way to cement their own power.
PDJT's response that he cannot control what other people say was exactly correct. Wallace seemed to be somewhat stunned/taken back by that for a second or two before the interview moved on.
Overall I'd say PDJT did very well, didn't take any crap and when appropriate seemed to genuinely disapprove of Wallace carrying the rest of the lying liberal lamestream media's water.
