To try or not to try:

"Biskupic writes that the constitutional text is, "When the President of the United States is impeached, the Chief Justice shall preside," which obscures the argument Roberts-excluders must make. The actual text is "When the President of the United States is tried, the Chief Justice shall preside." The argument must be that Trump is no longer the President of the United States, therefore there's no role for the Chief Justice. That also provides a foundation for an argument that there is now no occasion for a trial of impeachment — impeachment is a procedure for removing the President — and it is an abuse of power for the Senate to try the former President, deprived of the safeguard of the Chief Justice as a neutral arbiter."

There was a comment in the article that referenced the above:

"If the Chief Justice is required, then what Leahy is about to do is not a duty. Taking on a role that is not yours under the Constitution is an abuse of power."
Will Leahy be costumed in his horned animal skin shaman outfit?
