The White House on Friday brushed aside Sen. Hillary Rodham Clinton's call for the resignation of Defense Secretary Donald Rumsfeld. Clinton, in an interview Thursday with the Associated Press, called for President Bush to accept Rumsfeld's resignation over what she called a "failed policy" in Iraq. "I just don't understand why we can't get new leadership that would give us a fighting chance to turn the situation around before it's too late," the New York Democrat told the AP, adding, "The secretary has lost credibility with the Congress and with the people." White House spokesman Tony Snow said Friday there is no change in the president's position that Rumsfeld is the best person to lead the Defense Department. Snow declined to discuss why he believes Clinton is calling for Rumsfeld's ouster now. "I'll let her explain why she made the call," he said.
