by David Edwards and Nick Juliano, Raw Story June 20, 2008 Former White House spokesman Scott McClellan is testifying to the House Judiciary Committee about his new revelations on the exposure of CIA agent Valerie Plame and the Bush administration's "propaganda campaign" that led the country into war. McClellan was invited to testify after publication of his tell all memoir, What Happened: Inside the Bush White House and Washington's Culture of Deception. Judiciary Committee Chairman John Conyers said the revelations McClellan wrote about "may or may not constitute an impeachable offense." The revelation of a pre-war propaganda campaign was "a confirmation that the White House played fast and loose with the truth in a time of war," Conyers said to open the hearing. "Depending on how one reads the Constitution, that may or may not be an impeachable offense."
