it's pretty clear to me that most of the room realizes that the travel ban is to keep out reporters. but, despite knowing that, nobody states as much or challenges the spokesperson on it; instead, the discussion turns to press freedom, which produces the usual meaningless verbiage from the spokesperson, as she's announcing a policy meant to restrict press access. it's a conspiracy of silence, but a means of pressure nonetheless. they won't address the issue, but they'll coerce her into making a fool of herself.
what i'm unclear on is whether it's really seriously meant to be pressure, or just a cynical form of self-amusement.
