[Robert DeLong]

This is what I was referring to:

Article I, § 3, cl. 6, gives to the Senate “the sole power to try all impeachments,” requires that Senators be under oath or affirmation when sitting for that purpose, stipulates that the Chief Justice of the United States is to preside when the President of the United States is tried, and provides for conviction on the vote of two-thirds of the members present

However, rereading it again I realized the Chief Justice only presides of impeachment for the President only, not all impeachments. I hadn't read it in awhile. 8>)

Concerning the impeachment of a Vice President, a VP can only vote to break a tie. Since conviction requires two-thirds of the Senate voting to conviction there would be no tie breaker. But who does preside over a VP impeachment, still remains unanswered, Constitutionally. 8>)

[William Tell]

"But who does preside over a VP impeachment, still remains unanswered, Constitutionally. "

Actually, the question is not unanswered.

Again, from that Constitution thingy: "The Senate shall have the sole Power to try all Impeachments."

Lacking an exception that mentions the Vice President, then the Senate itself shall decide. Seems pretty clear to me.
