Why does Mueller prosecute Trump's friends for process, "crimes", but he REFUSES to prosecute Trump for, "colluding with the Russians"?

Easily explained.

There was no collusion with the Russians, therefore there is no crime of collusion to charge Trump with.

Prosecuting Trump is NOT Mueller's job

Mueller will NOT indict a sitting president because there are NO clear legal precedents to indict a sitting president, especially when the ACTING attorney general has NOT been confirmed by the Senate. The top lawyers, including the Supreme Court justices, are divided on whether a sitting president can be indicted or not.

No one except Mueller knows what he has or does not have.

All most of us can do is let Mueller do his job.

His friends all having secret dealings with Russia then lying about it is part of the coverup for Trump's collusion case, since the only possible reason they would do that is he asked them to do both.

Because it was a fake charge...no proof of it.

Because Trump never did that.

He REFUSES to? Do you have a sourcce for this that isn't your own butt?

Because he has nothing to charge Trump with.

Let's all face reality, here.

Anything solid Mueller has had got leaked.

The biggest "leak" lately was about a nude selfie.

That tells us a lot about the hand Mueller's playing.

The dominos are falling one by one. Mueller knows how to get to the big fish
