More about impeaching the vice president, but in general terms. In all their other wisdom, the Framers of the Constitution back in 1787 left a glaring oversight in the federal impeachment process. Article 1, Section 3 clearly states that the Chief Justice of the Supreme Court presides over presidential impeachment trials. Not explicitly said, though, is that the vice president, being the President of the Senate presides over all other impeachment trials.
The Vice President of the United States shall be President of the Senate, but shall have no Vote, unless they be equally divided…..
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.
U.S. Constitution, Article 1, Section 3
Constitutionally speaking, then, this would mean the vice president would technically preside over his own trial. Obviously he would have to recuse himself, so who would preside instead? Since the chief justice presides over presidential trials, my guess is that he would try the vice president as well.
Interesting enough, Ohio representative Dennis Kucinich back in April introduced a bill to impeach the vice president. The bill is currently dead in a House committee. Bill summary:
Sets forth articles of impeachment stating that Vice President Cheney: (1) has purposely manipulated the intelligence process to deceive the citizens and Congress of the United States about a threat of Iraqi weapons of mass destruction, and about an alleged relationship between Iraq and al Qaeda, to justify the use of the U.S. Armed Forces against Iraq in a manner damaging to U.S. national security interests; and (2) has openly threatened aggression against Iran absent any real threat to the United States, and has done so with the U.S. proven capability to carry out such threats, thus undermining U.S. national security.
