If the vice president is the subject of an impeachment, does the vice president have a vote in the Senate trial of which they are the subject?
Note: The constitution only mandates that the chief justice preside over impeachments of presidents, but not necessarily of others. (Article I, Section 3, Clause 6: ... When the President of the United States is tried, the Chief Justice shall preside: ....) Hence, this question isn't a duplicate of Does the Vice-President retain their tiebreaking vote during an impeachment trial of the President? as that question explicitly asked about the impeachments of Presidents.
