Like the story of the elephant/monkey above (very amusing, by the way, thanks for the laugh) their not well thought out plan, for ending this fell apart.
Their plan was,CONTINGENT upon PDJT firing Mueller team, Or agreeing to be deposed, leading to Impeachment for Obstruction or perjury.
At that point “nobody” would have been paying any attention to what happened to Gen. Flynn.
So, the prosecution kept delaying final sentencing. As long as Mueller investigation was “ongoing”, the threat to charge Flynn jr. was hanging, so Gen Flynn ‘went along’with the delays.
It was only when Mueller investigation was ended, that Gen Flynn was free to make his move, fire Covington, hire Sidney, and go on offence.
Like the elephant, the outcome was obvious, once Mueller team failed.
Just as Sidneys filings, and disclosures being made by DOJ (as a result of FISC court order on sequestering poisoned fruit, I suspect) are FORCING the Judge to ‘do the right thing’, Barr is NOT doing these disclosures cause he WANTS to (I suspect) but because he HAS to.
Again, IMHO once Mueller team failed to produce an excuse for Republicans in Senate to vote to convict, the Prosecutions case against Flynn was doomed, and they have spent all this time, delaying pulling the cork out, knowing the inevitable result.
Delay, delay, delay and hope against hope that tomorrow, something will change (like Ukraine impeachment, for instance).
Its human nature, when faced with a bad outcome, to delay as long as possible.
