Flynn is not going to be confirmed by the Senate for anything. Ironically he had been Trump's national sec advisor, and that job doesn't need senate confirmation.
The republicans still control the senate. Mitch McConnell is working on confirming a judge that the ABA said wasn't qualified to be a judge. And now Mitch is going to get him onto the court of appeals by a straight party line vote.
Imo there is a significant minority of gop senators who distrust Flynn, and with good reason, for any position requiring confirmation. His temperament is suspect, and that was why Bolton was never confirmed. Flynn's already shown ready to break laws for his own financial benefit. And at the heart of all that is his actions confirm his intelligence superiors concerns that while his intelligence gather is unsurpassed, he lacks the ability see how all facts interconnect with each other, so for example, what's happening in Russia affects Syria and both affect Iran and Iraq and all affect Saudi Arabia …..
I don't see any purpose to put him in jail though.
