|Michael Flynn with Michael Flynn Jr.,|
at Trump Tower during the transition
Flynn is cooperating with Mueller. Said Flynn, “My guilty plea and agreement to cooperate with the Special Counsel’s Office reflect a decision I made in the best interests of my family and of our country. I accept full responsibility for my actions.” Best interests of my family ... namely, Michael Flynn Jr., who was very involved too?
Flynn was passing requests to the Russians, and the Russians were sometimes complying, like in not too vigorously protesting the Obama administration's sanctions over election meddling in certain hope of seeing those sanctions lifted under Trump.
Some observers now consider that Trump himself has a legal exposure problem.
