Trump is ancillary to the whole thing. This was another instance of journalists all "independently confirming" from sources that were only the government. Specifically spooks, who burned them like always. And the journalists are doing the same thing constantly yet nobody cares how often they get burned by this because the original story is all that's wanted in the first place.
That Trump accurately called this one out just shows how bad the story was in this case. Yet people like Maddow and The Daily Beast (playing now in your town), not to mention random journalists on Twitter, all ran with it into the ground.
