President Bush has defended the decision to go to war in Iraq, following a highly critical Senate study concluding that key pre-war U.S. intelligence judgments about Iraqi weapons capabilities were unsupported or overstated.
The president also promised to work with Congress on reforming the nation's intelligence agencies.
The Senate Intelligence Committee report issued Friday accuses the intelligence community of treating ambiguous evidence as conclusive, ignoring contrary evidence and not challenging assumptions about Iraqi weapons.
The report singles out the Central Intelligence Agency, saying it prevented the sharing of some data with other agencies.
The bipartisan committee unanimously approved the more than 500-page report, but said it probably cannot complete a similar inquiry into the White House's possible role in the intelligence failures until after the presidential election.
