Colluded or duped?
If an FBI agent comes to a reporter and says, I have this report on Trump you might want to look at what is a reporter to do?
Does the reporter ask Has it been verified?
If you, as a reporter, want to get leaked to again by this agent you probably dont ask that question.
And given that this is the WAPO this reporter is probably ready to believe everything in the dossier.
I think it was easy to get the WAPO to take the dossier at face value. I dont think it was necessary for the reporter to be part of a conspiracy to get the reporter to do what the FBI agent wanted him to do.
At the Times wasn’t the reporter having sex with multiple members of the US government for “scoops”?
Since the reporter never screamed holy hell about being used (s)he was a willing yellow journalist.
