The Bush administration's firing of nine U.S. attorneys has left Attorney General Alberto Gonzales clinging to his job while accusations of undue partisanship at the Justice Department intensify. Gonzales has admitted misleading Congress in minimizing the White House's involvement in the dismissals — an unprecedented step midway through a president's term. Some of the fired prosecutors say they may have been targeted for their handling of politically charged corruption and vote-fraud cases, but Gonzales and his former top aide deny any political motivations. Another former Gonzales aide, however, has admitted taking political affiliation into account in some Justice Department hiring decisions. Democrats in Congress want top White House aides to testify about the firings. Many Democrats — and a handful of Republicans — have called for Gonzales to resign. But he is vowing to stay, and President Bush says he has confidence in his longtime friend and aide.
