Consider a few facts.
The case has only been ongoing for three years, not a decade.
For the first 23 months of the case, Flynn had lawyers who appear to have actively cooperated with the prosecution, without telling Flynn.
Powell has had the case 13 months.
Powell has done more for General Flynn in those 13 months, than his previous lawyers did in the previous two years. Much of what Powell has had to do, was undo the damage done by previous counsel.
Wasn’t the problem or one of them, was he was lobbying for a truckish organization that was on the bad guys list? I haven’t followed this to closely. Flynn was trying to monetize his military experience. What did he actually end up pleading guilty too? His lawyers really did that how are they not in hot water and why did he pay them? Very screwy
