CNN's John Roberts talked with Politico's Mike Allen about his scoop on Scott McClellan's new book which is filled with "explosive allegations" against the Bush Administration. McClellan's writes that the Bush Administration used propaganda to sell the Iraq war and that Bush Administration officials encouraged him to lie in the Valerie Plame scandal.

Former top Bush advisors Karl Rove and Fran Townsend have disputed McClellan's claims. Rove accused McClellan of sounding like a "left-wing blogger."
