A precedent had been set when a judge was impeached awhile back. The constitution allows this.
The constitution allows this.
No it most certainly does not!
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.
"SHALL" means he must preside over an Impeachment Trial.
Shall is ironclad. It's not the same as may, or might.
Article 1, Section 3: 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.
Presiding officer for the impeachment of a judge, cabinet member or other official is not specified, but for a president, it is made mandatory that the presiding officer is the Chief Justice. Roberts can resign if he feels so strongly about doing his job, but the Constitution doesn't contain a "I don't want to" clause.
He resigned to avoid impeachment. Not the same thing.
