Each Senator sitting in judgment at the trial of articles of impeachment must take an oath as provided by Senate Impeachment Rules of March 2, 1868 (involving President Andrew Johnson). If President Trump is impeached by the House, each Senator will pledge to act in accord with this oath:
Form of oath to be administered to the members of the Senate sitting in the trial of impeachments: I solemnly swear (or affirm, as the case may be,) that in all things appertaining to the trial of the impeachment of ______________, now pending, I will do impartial justice according to the Constitution and laws: so help me God.While I'm confident that each senator will take the oath, I fear that too few will honor its requirement.
