His government is leaking like a sieve, and this isn't happening for no reason. He is not in control.
How do you know that it is his government that is doing it?
Recordings or transcripts or whatever of his phone calls to Mexico and Australia illegally appear in newspapers. So how do you know the leaks are from his government? [there may have beensomething about it that I have not seen. In which case you can point it out!].
So how can you square that the leaks are right but the news about them is fake
Partly done above, plus he says that CNN in particular plus a couple of other publications[washington post is one?]are writing fake news.
The russia stuff for example. Most or all of it.
