But Sen. Pat Roberts of Kansas said the CIA and State Department had provided a "good faith response" and the committee expected to receive "a quantity of documents" from both agencies by the end of the day.

"The White House has not met today's deadline. I am hopeful that the White House will recognize the importance of the committee's efforts and comply as soon as possible," Roberts said in a statement.

The Senate Intelligence Committee this week sent letters to top administration officials demanding documents be turned over and interviews with officials be scheduled by the deadline.

Congressional officials said that step was intended to prod the administration to provide information the panel had requested as long as five months ago for its review of the quality of US intelligence on Iraq leading up to the war.

At this point more drastic steps such as subpoenas were not being considered, but Sen. John Rockefeller said if the response was lacking he would be prepared to take such action.

"We're not kidding around on this," the West Virginia Democrat told Reuters. Setting the deadline was "meant to be a very strong signal to them that we're tired of waiting. This is the nation's business, there is a lot at stake," he said.

Critics have said President Bush and his administration may have exaggerated the threat from Iraq's banned weapons to gain support for the war. No biological or chemical weapons have been found, nor any solid evidence that Iraq was resurrecting its nuclear program.

White House spokesman Scott McClellan said that even though the Senate committee has no jurisdiction over the White House, it has been working to help with the panel's Iraq review. "We are talking with them and we will continue working with them," he said from Crawford, Texas.

Republicans on the Senate Intelligence Committee want to finish the review by year end and focus on the intelligence agencies, while Democrats are seeking a broader scope to include a look at how the White House used the intelligence.
