by the House and being tried and convicted by the Senate. He certainly is enough of a cocky Ba&0$$D to do that, even if it would put his party in more jeopardy than it already is.
In this case, I don't think * could pardon Cheney, but if anyone can provide relevant information about this, please do. (*, however, might BELIEVE he can pardon Cheney, and might even try, and who know what would happen? * has gotten away with violating law after law, simply because he BELIEVES he can.)
http://en.wikipedia.org/wiki/ImpeachmentAt the federal level, both the executive branch and the judiciary may be impeached, though different standards apply. For the executive branch, only those who have allegedly committed "treason, bribery, or other high crimes and misdemeanors" may be impeached. Although treason and bribery are obvious, the Constitution is silent on what constitutes a "high crime."

The impeachment procedure is in two steps. The House of Representatives must first pass "articles of impeachment" by a simple majority. (All fifty state legislatures as well as the District of Columbia city council may also pass articles of impeachment against their own executives). The articles of impeachment constitute the formal allegations. Upon their passage, the defendant has been "impeached."
Next, the Senate tries the accused. In the case of the impeachment of a President, the Chief Justice of the United States presides over the proceedings. Otherwise, the Vice President, in his capacity of President of the Senate, or the President pro tempore of the Senate presides. This would include the impeachment of the Vice President him- or herself.
In order to convict the accused, a two-thirds majority of the senators present is required. In the case of current office-holders, conviction automatically removes the defendant from office. Following conviction, the Senate may vote to further punish the individual by barring him from holding future federal office (either elected or appointed). Despite a conviction by the Senate, the defendant remains liable to criminal prosecution. It is possible to impeach someone even after the accused has vacated his office in order to disqualify the person from future office or from certain emoluments of their prior office (such as a pension.) If a two-thirds majority of the senators present does not vote "Guilty" on one or more of the charges, the defendant is acquitted and no punishment is imposed.
