trial not legal no chief justice Article I, Section 3, Clause 6:
The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two thirds of the Members present.
FYI, the one link I was able to start watching (and then reported) is for an ep of a Canadian show called “WingMen” — not a Finnish show called “Wingman / Luottomies.”
I can’t get the other links to load, so I don’t know if any are OK or if all are incorrect.
