United States Constitution, Article 2, Section 2: The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any subject relating to the Duties of their respective Offices, and he shall have Power to Grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.
Emphasis mine.
Impeachment at this juncture and based on the revelations over , regardless of the arguments against it, is a moral imperative. Bush will no doubt pardon anyone that has any connection to any wrongdoings, and even though Obama and Clinton talk about investigating the crimes committed in this administration, I think we all probably know how difficult it will be to get anything meaningful done in that respect, although if either of them do, I will be so very pleasantly surprised.
