the lockdown is because they have to find out where the leaks are coming from.McMasters' comment - and the current WH lockdown - have me inclined to give WaPo the benefit of the doubt.
The Post is not a rag. I seriously doubt a reporter there would make this up, or use sources who were unreliable. The idea of Trump boasting about secrets seems much more plausible.
I don't think you understand where Macmaster's loyalties lie- he's not some bureaucrat,he's a lieutenant general
