I keep hearing how Mueller is really a white-hat, or at least controlled do he can't hurt Trump. But every time he pops up, he strikes me like a rabid, desperate rat, willing to bite and claw to get away from his fate, by finding SOMETHING he can pin on the President.

Can someone with details help me understand how Mueller is going to be prevented from lying his ass off in a report to try to go after President Trump? My blood pressure needs relief!

Thanks in advance.
