So now you've shifted your position from a crime needing to be committed to appearing sketchy.
Do you believe that appearing "sketchy" gives the government the right to pry into every aspect of your life? Even if they have that right, does that make it morally right? If so, we might as well live in Orwellian China.
It is also proven that Mueller has hired numerous Democrat lawyers on his team. I'm sure they wouldn't have any kind of reason to take down Trump.
Also, quit acting like firing Comey was a big red flag to anyone, because it simply isn't/wasn't. Remember that Rod Rosenstein oversees the Mueller probe, not the FBI director (Comey at the time). If Trump really wanted to end the Russia probe, he would've fired RR or Mueller directly.
