United States Constitution

The founders mention impeachment six times in the Constitution. They weren't kidding. They really meant it. They wanted us to use it.

Article. 2, Section. 4. " The President, Vice President and all civil Officers of the United States,shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors."

Notice they didn't say "might be removed", or "could be removed". They said "shall be removed."

Treason - ordering the outing of an undercover CIA officer, and then commuting the sentence of the scapegoat that got caught. (See Joe Wilson, Valerie Plame, Scotter Libby)

Bribery - over 2 billion in grants dispensed by the "White House Office of Faith-Based and Community Initiatives"
(they violated the Establishment Clause of the First Amendment with this one as well as the bribery)

Other High Crimes and Misdemeanors - The NSA warrant-less wiretapping program was clearly in violation of FISA law as has been ruled by Judge Anna Diggs Taylor. This one is so obvious. Bush bragged on TV, that he authorized and reauthorized this program 30 times. How can we allow him to remain in office?
