The same Washington Post frontpage article that pushed the "imminent threat" myth today also reports the following:
Before the war, he [Vice President Cheney] traveled to CIA headquarters for briefings, an unusual move that some critics interpreted as an effort to pressure intelligence officials into supporting his view of the evidence. After the war, when critics started questioning whether the White House relied on faulty information to justify warâ€¦.
Deliberate or not, this statement strongly suggests that Cheney's visits to the CIA contributed to the "faulty information" used to "justify" the war. What's more, the Post apparently decided that the following conclusions from the Senate's 2004 bipartisan Report on the U.S. Intelligence Community's Prewar Intelligence Assessments on Iraq were too insignificant to mention.
Conclusion 83 (p. 284)
The Committee did not find any evidence that Administration officials attempted to coerce, influence or pressure analysts to change their judgments related to Iraq's weapons of mass destruction capabilities.
Conclusion 84 (p. 285)
The Committee found no evidence that the Vice President's visits to the Central Intelligence Agency were attempts to pressure analysts, were perceived as intended to pressure analysts by those who participated in the briefings on Iraq's weapons of mass destruction programs, or did pressure analysts to change their assessments.
