The White House reversed itself and promised the Senate Intelligence Committee access to all materials requested for its inquiry into prewar intelligence on Iraq, the committee chairman said Sunday.

A White House spokesman remained noncommittal, promising “a spirit of cooperation” but no specifics. Spokesman Trent Duffy reiterated administration doubts about the committee’s jurisdiction over the White House.

The CIA and the State Department already turned over large quantities of documents ahead of the committee’s deadline last Friday, and more material is coming, Sen. Pat Roberts, R-Kan., said.

White House acquiescence, on behalf of the National Security Council, came to committee staff members late Friday along with notification from the Pentagon that it also would cooperate, Roberts said on CNN’s “Late Edition.”

The committee’s top Democrat, Sen. Jay Rockefeller of West Virginia, said he wants “to see the documentation before … I’m satisfied. I want to know that we really have it in hand.”

Roberts, who was in Kansas, spoke just after Rockefeller, in Washington, had complained that the White House and Defense Department were “being very resistant.”

Rockefeller had just finished saying, “We have to have those documents. We’re going to get those documents, one way or another,” when Roberts was asked if he concurred.
