Why Is This Allowed?

Why is the Dumocrat Party allowed to have a “special prosecutor” to be appointed (at $20 million dollars of government expense, so far) whose ONE JOB is to “take down” a sitting president? Why does that sitting president not stop funding this scheme to remove him from office for anything they can find, or manufacture? This would never be allowed in any country run by a dictator, which liberals claim Trump has become. When Mueller was appointed, he was appointed against the rules, which say a CRIME must be there to be investigated. Collusion with the Russians is NOT a crime, even if it were true. Next, Mueller hired 13 (or more) “investigators” for his staff, all of whom are KNOWN Trump haters, and they get paid handsome salaries to find, or manufacture, anything they can to cast aspersions on this sitting president. Mueller has ruined the lives and reputations of several people in his quest, for things done way BEFORE their association with Trump, and his “investigation” has gone far afield from the original mandate to “prove” Trump’s collusion with the Russians to get elected, something they’ve worked hard on for almost 2 years, while finding NO EVIDENCE of any “collusion, with the Russians, or anybody else. Meanwhile, there is CREDIBLE EVIDENCE, being ignored, that Hillary Clinton DID “collude with the Russians, in her unsuccessful effort to get elected. (Just common sense)
