My God, this guy is a mumbling, fumbling, idiot.
First of all, he is presenting this idea that Mueller "has to present SOMETHING". No, he doesn't. That's just a flat out lie. He has to do the job he was assigned, and that is all.
Flynn was in the shit. They had him from multiple direction, and his son. They didn't have to come to an agreement with Flynn. They had enough "dirt" on him to put him in jail for most of the rest of his life, and his son for years. So, for a plea agreement to make any kind of sense, Flynn had to have something of AT LEAST equal value to give. We have barely heard what Flynn has given...and to assume all Flynn is is some fall guy so Mueller can show progress is laughable wishful thinking.
The only thing this guy said that makes sense is "take the 5th.." to avoid where Flynn is. That is somewhat true. But, it also gives the impression that there is something to hide. So, if you talk to the FBI, you had better not be lying or you will end up in being prosecuted.
The FACT that Trump is a pathological liar, it would not surprise me AT ALL if both Jr. and Kushner were encouraged to lie to hide how much cooperation there was between Russia and the Trump campaign...which means they will be in this same situation...either make a deal and turn on Trump Sr., or go to jail for a LONG TIME. Their choice...
