Interesting sidenote on VP resignations:
As more details emerge from the shadows, one has to ask why GW Bush never initiated an impeachment of Dick Cheney or asked him to resign. Check this out: sourcewatch.org
1. "The 9/11 Commission found that, from the White House situation room, Cheney warned the president that a 'specific threat' had targeted Air Force One, prompting Bush to spend the day hiding in the bunker at Offut Air Force Base in Nebraska. There was no specific threat. In Bush's absence, Cheney, implying an authorizing telephone call from the president, took command of the nation's response to the crisis. There was no authorizing telephone call. The 9/11 Commission declined to make an issue of Cheney's usurpation of powers, but the record shows it,"
2. The Cheney-Rumsfeld Cabal, led by Vice President Dick Cheney and Secretary of Defense Donald H. Rumsfeld, hijacked U.S. foreign policy by circumventing or ignoring formal decision-making channels, according to Lawrence Wilkerson, Chief of Staff to Secretary of State Colin L. Powell, Jim Lobe reported for the Inter Press Service, October 20, 2005. Wilkerson has also charged that, as national security adviser, Condoleezza Rice was part of the problem by not ensuring that the policy-making process was open to all relevant participants,"
3. "The outing of CIA operative Valerie Plame was but one element of a much larger conspiracy. From 2002-3, Rumsfeld and Cheney coordinated a network--inside and outside of government--to plan the invasion of Iraq. The network operated in secret because the case made to Congress and the U.N. was false. The cabal then forced its agenda on the career military, intelligence, and diplomatic staff, resulting in numerous removals and resignations. ... (There were) four primary cells of the cabal: the headquarters, centered in the Vice President's office; the communications shop at the White House; the intelligence and war planning shop called the Office of Special Plans; and the informal coordination network housed at the American Enterprise Institute."
