On Thursday, May 10, 2007, Lawrence Wilkerson, speaking on National Public Radio, proposed impeaching President George W. Bush and Vice President Dick Cheney. Here's the audio.

Wilkerson is a Retired Army Colonel, the former Chief of Staff at the State Department from 2002 to 2005 under then Secretary of State Colin Powell, a Vietnam War veteran, the former Acting Director of the Marine Corps War College at Quantico, and currently a teacher of national security at William and Mary College.
After an interruption, Wilkerson continued: "The language in that article, the language in those two or three lines about impeachment is nice and precise – it's high crimes and misdemeanors.
