You could be right. I have no idea.
Another point I find hard to believe in that 4chan post is the bit about Mueller using FBI agents he knew in the past with evidence of Hillary’s wrongdoing.
Mueller doesn’t get to pick the FBI agents assigned to the Special Counsel investigation. That would be Andrew McCabe who decides that. The same Andrew McCabe whose wife got something like $800,000 from Clinton bagman Terry McAuliffe for her run for a seat in the Virginia legislature. A ridiculous amount of money for such a small position.
McCabe should be the one investigated, not overseeing the FBI team assigned to the Special Counsel.
