Art 2, Sect 4 clearly indicates that Potus shall be removed from office after being impeached. That is not possible. Trump is not Potus.
Art 1 additionally says the Chief Justice presides when the Potus is being impeached. Since Trump isn’t the potus, then potus isn’t being impeached. Therefore, the CJ does not preside.
Who will?
If he does,is that an accidental admission that Trump is really the Potus?
If the Senate is going to try Trump, then until he is “removed from office” they need to remove Biden from the White House.
