WASHINGTON — In a long-delayed report, the Senate Intelligence Committee yesterday rebuked President Bush and Vice President Cheney for making pre-war claims — particularly that Iraq had close ties to Al Qaeda — that were not supported by available intelligence.

The report, which was opposed by most Republicans on the panel, accuses the president and other members of his administration of repeatedly exaggerating evidence of an Al Qaeda connection to take advantage of the charged climate after September 11. It amounts to the most-pointed reproach to date of the Bush administration’s use of intelligence to build the case for the Iraq war. But the document stops short of calling for any follow-up investigation or sanction.

“In making the case for war, the administration repeatedly presented intelligence as fact when in reality it was unsubstantiated, contradicted, or even nonexistent,” Senator Rockefeller IV, a Democrat of West Virginia and chairman of the intelligence panel, said. “Sadly, the Bush administration led the nation into war under false pretenses.”

In a second report, the committee provided new details on clandestine, post-September 11 meetings between Defense Department officials and Iranian dissidents seeking support for a plan to overthrow the Islamic regime. In that document, the committee faulted a national security adviser, Stephen Hadley, and others for their roles in an effort that was hidden from the CIA.

The committee’s 170-page report on the Bush administration’s case for war reads like a catalog of erroneous claims. The document represents the most detailed assessment to date of whether those assertions were backed by classified intelligence reports available to senior officials at the time.
