President Trump’s supporters and enablers are stretching credulity in their efforts to protect their favorite commander in chief’s tenure and reputation. If President Trump commits a crime, like shooting or jailing his political rival(s), of course he could be charged with murder or other crimes and tried in a criminal proceeding in state or federal court depending on where the crime occurred. He does not first have to be impeached in the House and convicted in the Senate; that appears nowhere in the Constitution or in the nation’s jurisprudence. In my opinion, that’s a Giuliani/Kavanaugh/McConnell myth. On the other hand any President of either party should not be subjected to a series of political/judicial persecutions as President Clinton was by Judge Starr, Speaker Gingrich and their associates (among them Supreme Court nominee Brett Kavanaugh). If President Trump descends from his fitful rages into a full fledged, disabling mental illness or has a heart attack and can no longer fulfill the duties of his office, the 25th Amendment is the right recourse for his cabinet to remove/suspend him from office. If indeed he and President Putin and others cooked up some deals to finance him, and get him elected, and he’s been selling our nation and its allies down the river since acceding to the presidency, the right remedy is impeachment and conviction then removal from office.
As yet there is no evidence he has done any of the above, so the most important steps for all Americans is to let the Mueller investigation take its course and to vote in the November elections.
