What charges?
Here's Flynn's problem in a nutshell (from his plea agreement) ...
Note the item I highlighted.
DEFENDANT'S ACCEPTANCE
The preceding statement is a summary, made for the purpose of providing the Court with a factual basis for my guilty plea to the charge against me. It does not include all of the facts known to me regarding this offense. I make this statement knowingly and voluntarily and because I am, in fact, guilty of the crime charged. No threats have been made to me nor am I under the influence of anything that could impede my ability to understand this Statement of the Offense fully.
I have read every word of this Statement of the Offense, or have had it read to me. Pursuant to Federal Rule of Criminal Procedure 11, after consulting with my attorneys, I agree and stipulate to this Statement of the Offense, and declare under penalty of perjury that it is true and correct.
The document is dated 11/30/17. There's a signature underneath all this ... from a guy named Michael Flynn.
He signed this document UNDER PENALTY OF PERJURY.
