Again, either the FBI provided fabricated 302s, or Ben Smith fabricated a story.
THAT’s the real news, IMHO (i.e. the answer to the question):
“Who lied?”
The “two senior law enforcement sources” and on their 302s, or Ben Smith?
IMO the takeaway from this is not who lied. Normally a reporter falls back on the 1st A. and refuses to name sources so bringing Ben Smith in for questioning would be a futile fishing expedition. He just solved that problem for the DoJ by publishing his sources.
Now they can question him without that issue in the way. It’s still a crime even if the FBI provided false notes to Smith but according to Smith they were real 302s which had their false impressions in them. That makes them real FBI notes as far as the law is concerned.
