Trump is an absolute embarrassment to our nation.
In our #metoo culture, and Trump admitting he would "grab them by the pussy", why hasn't this pervert been charged with sexual assault yet? Are women complaining being killed off by some presidential decree?
There's not really that great of presdence for criminal charges (or civil charges) brought against a sitting president. Normally, criminal charges are processed through Congress.
However, Congress is stacked with the same party as Trump... they're refusing to remove their own man.
Also, the Supreme Court is being stacked. A couple decades ago, I'm pretty sure the SCOTUS would rule that the president of the United States can stand before a trial. If the GOP (and Trump) gets their way, Trump will have nearly unlimited authority.
It doesn't help that Trump's a pathological liar. For example, from one of his speeches recently, they broke out everything he said.
