May 26 (Bloomberg) -- The Pentagon has promised to give the Senate Armed Services Committee a ``complete and certified'' copy of the military's primary investigative report into abuses at Abu Ghraib prison.

The document will be provided as quickly as possible, according to correspondence between the Pentagon and Senator John Warner, a Republican from Virginia who heads the Armed Services Committee.

The missing pages include a report written in September by Major General Geoffrey Miller, the deputy commander of detainee operations at Guantanamo Bay, Cuba, after his visit to Abu Ghraib and recommendations for improving interrogations there, according to a summary of the missing pages prepared by Senate staff. They also included draft findings of Miller's visit given to Defense Secretary Donald Rumsfeld, according to the summary.

Miller's report and recommendations served, according to press reports, as the basis for stricter interrogation methods, including the use of guard dogs against detainees, that critics say contributed to a climate of abuse that lead to the prison scandal.

Two-Foot Report

The Pentagon, starting with a May 7 Senate Committee hearing with Rumsfeld, made a point of emphasizing the sheer volume of the report by Army Major General Antonio Taguba -- an almost two- foot-high stack of paper displayed in hearing rooms -- as a signal the military was providing full disclosure of the prison scandal.

Still, Senate committee staff told the Pentagon's legislative liaison office May 20 that ``some pages were either missing, out of order or mislabeled'' in the copy provided to the committee, Assistant Secretary for Legislative Affairs Powell Moore wrote May 25 to Chairman Warner.

Some press accounts said that as many as 2,000 pages were missing, a perception that was inaccurate, Pentagon spokesman Larry DiRita told reporters today.

``The perception that was left was unfortunate, which is that we were somehow trying to withhold something from the committee,'' he said. ``That certainly is not the case.'' Some of the documents were mislabeled or weren't ``unique'' to the investigation, such as Army field manuals, he said.

The Pentagon, ``in the interest of providing a complete and certified copy,'' has contacted Taguba, who is now back in Kuwait, and asked him to provide a complete copy of the report, Moore wrote Warner.

Warner in a memo to committee members today said he was satisfied there was no Pentagon cover-up.

``Over the past several days, Committee staff has, at my direction, been working with the department to ensure that the Taguba report is a full and complete copy, including all annexes and enclosures,'' Warner wrote.

``I continue to believe that the Department is working in good faith to provide a complete copy,'' he wrote.
