You act as if Flynn was just some dude in Appalachia who was visited by the FBI as part of an investigation into marijuana farms and crystal meth labs that were found in a nearby forest.
Flynn was a senior executive branch appointee who was being interviewed by the FBI as a matter of course during the background check as part of the nomination process.
And, you have just learned that an interview “in a matter of course” should never be given.
I already knew it. Now you do too.
