And you're shading with cherry picking. The Mueller appointment didn't happen in a vacuum, and there was far less known about the dossier and many other things Clinton.
That's why the Dems and their allies moved so quickly, starting with Flynn. They wanted to stop something before it's started. They knew the dossier shenanigans and their connection to Clinton would come out.
Paint the sky whatever color you want, but it doesn't fit the reality of the situation.
Trump fired Flynn (who is a lifelong democrat), for lying to Pence, months before Mueller was appointed. The FBI didn’t charge him, Mueller did, many months, later, after Flynn began to voluntarily sing. Flynn knew he had lied and began offering Mueller information almost immediately upon being questioned. Neither he, nor his son, were threatened with indictment to secure his cooperation. We know this, because his attorney stated it in the plea agreement filing for sentencing. Mueller charged him with lying, despite the other options he had. It was the least of the potential charges and he recommended no jail time, because of the extensive information Flynn provided. So much for being railroaded. That’s the reality.
