Osama Bin Laden There is renewed frustration in Washington that Osama bin Laden and al Qaeda appear to have survived intense attacks by U.S. forces in Afghanistan. Over the weekend, the Arab satellite news network, Al-Jazeera, aired an audiotape in which an al Qaeda spokesman said the United States faces more attacks. The spokesman said 98 percent of al Qaeda's leaders have survived. Meanwhile in Washington, some members of Congress are starting to blame the Bush administration for letting bin Laden get away.
