Seymour Hersh writes that, according to an unnamed Pentagon adviser, "[OSP] was created in order to find evidence of what Wolfowitz and his boss, Defense Secretary Donald Rumsfeld, believed to be true—that Saddam Hussein had close ties to Al Qaeda, and that Iraq had an enormous arsenal of chemical, biological, and possibly even nuclear weapons (WMD) that threatened the region and, potentially, the United States. [...] 'The agency [CIA] was out to disprove linkage between Iraq and terrorism,' the Pentagon adviser told me. 'That’s what drove them. If you’ve ever worked with intelligence data, you can see the ingrained views at C.I.A. that color the way it sees data.' The goal of Special Plans, he said, was 'to put the data under the microscope to reveal what the intelligence community can’t see.'" (Hersh, 2003)
These allegations are supported by an annex to the first part of Senate Intelligence Committee's Report of Pre-war Intelligence on Iraq published in July 2004. The review, which was highly critical of the CIA's Iraq intelligence generally but found its judgments were right on the Iraq-al Qaeda relationship, suggests that the OSP, if connected to an "Iraqi intelligence cell" also headed by Douglas Feith which is described in the annex, sought to discredit and cast doubt on CIA analysis in an effort to establish a connection between Saddam Hussein and terrorism. In one instance, in response to a cautious CIA report, "Iraq and al-Qa'eda: A Murky Relationship", the annex relates that "one of the individuals working for the [intelligence cell led by Feith] stated that the June  report, '...should be read for content only - and CIA's interpretation ought to be ignored.'" (Report, 2004)
Douglas Feith called the office's report a much-needed critique of the CIA's intelligence. "It's healthy to criticize the CIA's intelligence", Feith said. "What the people in the Pentagon were doing was right. It was good government." Feith also rejected accusations he attempted to link Iraq to a formal relationship with Al Qaeda. "No one in my office ever claimed there was an operational relationship", Feith said. "There was a relationship."
In another instance, an "Iraqi intelligence cell" briefing to Rumsfeld and Wolfowitz in August 2002 condemned the CIA's intelligence assessment techniques and denounced the CIA's "consistent underestimation" of matters dealing with the alleged Iraq-al Qaeda co-operation. In September 2002, two days before the CIA's final assessment of the Iraq-al Qaeda relationship, Feith briefed senior advisers to Dick Cheney and Condoleezza Rice, undercutting the CIA's credibility and alleging "fundamental problems" with CIA intelligence-gathering. As reported in the conservative British newspaper The Daily Telegraph, "Senator Jay Rockefeller, senior Democrat on the [Senate] committee, said that Mr Feith's cell may even have undertaken 'unlawful' intelligence-gathering initiatives." (Coman, 2004)
In February 2007, the Pentagon's inspector general issued a report that concluded that Feith's office "developed, produced, and then disseminated alternative intelligence assessments on the Iraq and al Qaida relationship, which included some conclusions that were inconsisent with the consensus of the Intelligence Community, to senior decision-makers." The report found that these actions were "inappropriate" though not "illegal." Senator Carl Levin, Chair of the Senate Armed Services Committee, stated that "The bottom line is that intelligence relating to the Iraq-al-Qaeda relationship was manipulated by high-ranking officials in the Department of Defense to support the administration's decision to invade Iraq. The inspector general's report is a devastating condemnation of inappropriate activities in the DOD policy office that helped take this nation to war." At Senator Levin's insistence, on April 6, 2007, the Pentagon's Inspector General's Report was declassified and released to the public.
Feith stated that he "felt vindicated" by the report. He told the Washington Post that his office produced "a criticism of the consensus of the intelligence community, and in presenting it I was not endorsing its substance."
Feith also said the inspector general's report amounted to circular logic: "The people in my office were doing a criticism of the intelligence community consensus", Feith said. "By definition, that criticism varied. If it didn't vary, they wouldn't have done the criticism."
Journalist Larisa Alexandrovna of The Raw Story reported in 2006 that the OSP "deployed several extra-legal and unapproved task force missions" in Iraq both before and after the beginning of combat. The teams operated independently of other operations, occasionally causing confusion on the battlefield. The teams appear to have had a political rather than military mission; specifically, to find Iraqi intelligence officers willing to come up with evidence of WMD in Iraq whether or not such weapons actually existed:
According to the UN source, the intelligence officers did not cooperate with the OSP forces because they were aware that forged WMD evidence "would not pass the smell test and could be shown to be not of Iraqi origin and not using Iraqi methodology."
Larry Franklin, an analyst and Iran expert in the Feith office, has been charged with espionage, as part of a larger FBI investigation (see Lawrence Franklin espionage scandal). The scandal involves passing information regarding United States policy towards Iran to Israel via the American Israel Public Affairs Committee. Douglas Feith's role is also being investigated.
According to The Guardian, Feith's office had an unconventional relationship with Israel's intelligence services:
Allegations have also been made that Pentagon employees in the Feith office have been involved in plans for overthrowing the governments of Iran and Syria.
When Former NSA Chief General Michael Hayden testified before the Senate Hearing on his nomination as Director of Central Intelligence in May 2006, he was questioned by Senator Carl Levin (D-MI) on the pressure exerted by the Office of Special Plans on the intelligence community over the question of Saddam's links to al-Qaeda. Hayden explained that he was not comfortable with the OSP's analysis: "I got three great kids, but if you tell me go out and find all the bad things they've done, Hayden, I can build you a pretty good dossier, and you'd think they were pretty bad people, because that was I was looking for and that's what I'd build up. That would be very wrong. That would be inaccurate. That would be misleading." He also acknowledged that after "repeated inquiries from the Feith office" he put a disclaimer on NSA intelligence assessments of Iraq/al-Qaeda contacts.
