Poll: Many Suspicious of Bush

Two-thirds of Americans think the Bush administration is hiding something about what it knew before Sept. 11, while just over a fifth think the administration is "telling the entire truth," a CBS News poll released Tuesday said. But most, 62 percent, don't believe congressional hearings are warranted on the situation.

Almost half think Democrats' questions to the White House about its handling of the Sept. 11 attacks are appropriate, and a third disagreed. The poll of 681 adults was taken Sunday and Monday and has an error margin of plus or minus 4 percentage points.

Among the poll's other findings:

–By a narrow margin, 43 percent to 30 percent felt the Bush administration is hiding something the public needs to know.

–A fourth placed a lot of blame on U.S. Middle East policies for the Sept. 11 attacks, while another half said they placed some blame on the policies.

–Almost half said the CIA and FBI had information before the attacks that could have prevented them, while a third said the agencies did not.
