John W. Dean, former President Richard Nixon's White House lawyer, says President George W. Bush's domestic spying exceeds the wrongdoing that toppled his former boss. Bush, Dean told the Senate Judiciary Committee on Friday, should be censured and possibly impeached. "Had the Senate or House, or both, censured or somehow warned Richard Nixon, the tragedy of Watergate might have been prevented," Dean said. "Hopefully the Senate will not sit by while even more serious abuses unfold before it." Republicans and their witnesses rejected the comparison between Watergate and Bush's wiretapping program and attributed Democratic Sen. Russell Feingold's censure resolution to posturing in a year of congressional elections. "Quit trying to score political points," Sen. Orrin Hatch shot across the aisle at committee Democrats.
