In guesstimated chronological order -- likely wrong in places:
1. Flynn omitted payments received from Russian entities from disclosure form.
2. Flynn operated as a Turkish agent without following disclosure law.
3. Flynn lied to Pence. Pence repeated that lie to the press.
4. The moment the lie was public, Flynn is setup for blackmail by the Russians. Obviously.
5. Trump repeated Flynn's lie to the press. I don't think we have specific evidence that Flynn lied to Trump. Maybe Trump was parroting what he heard. Either way, Flynn allowed that lie to stand.
6. Flynn lied to the FBI. The notion that he was a poor little baby who needed to be informed that lying to the FBI is naughty is flat out surreal.
7. Flynn was fired by Trump, for the stated reason that Flynn lied.
8. Flynn admitted the truth only when presented the precise text of intercepted communication with Russian actor.
9. Flynn admitted lying when he plead guilty.
Knowing this, presumably, Rep. Matt Gaetz (R-FL) says:
Gaetz said:
I'm not troubled by Flynn's conduct.
