Flynn knows a great deal about the FBI, esp. since Mueller left, so I wouldn’t be surprised if he’s been working with the team all along. Another piece falls into place.
Flynn could be disconnecting himself from Trump's lawyers to protect the Prez in some ploy or other that the lawyers have hatched up.
Don't forget if the General is sentenced to a long stretch at Club Fed...only the Donald can pardon him....not Mueller!
