I don't think so.  But I don't know.  When searching for Supreme Court Rules, I found this interesting From the Constitution: From Article 3 Section 2: In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make. I note, not the House or the Senate.  Is the impeachment not about the Ukraine Ambassador Yovanovich being fired really?
