Of course, reporting like this is less WaPo and more the reporters, so odds are they could report something like this anywhere. I F Stone's post-blacklist career is, as ever, proof that a reporter without a platform can do great reporting.
So yeah, credit to WaPo--but not too much.

I should point out what should be obvious: The establishment media, in reporting this, could have as easily pointed Trump was lying, maybe even delusional, as easily as Greene did but, as always, took a pass on doing so.
