The officials work or had worked in the State Department, the CIA and the National Security Council in a senior capacity and had direct knowledge of the Vice President's campaign to discredit Wilson.
The officials said they decided to speak out now because they have become disillusioned with the Bush administration's policies regarding Iraq and the flawed intelligence that led to the war.
They said their roles, along with several others at the CIA and State Department, included digging up or "inventing" embarrassing information on the former Ambassador that could be used against him, preparing memos and classified material on Wilson for Cheney and the National Security Council, and attending meetings in Cheney's office to discuss with Cheney, Hadley, and others the efforts that would be taken to discredit Wilson.
A former CIA official who has worked in the counter-proliferation division, and is familiar with the undercover work Wilson's wife did for the agency, said Cheney and Hadley visited CIA headquarters a day or two after Joseph Wilson was interviewed on CNN.
"The underlying objective, as I see it, the more I look at this, is less and less disarmament, and it really has little to do with terrorism, because everybody knows that a war to invade and conquer and occupy Iraq is going to spawn a new generation of terrorists," Wilson said in a March 2, 2003, interview with CNN.
"So you look at what's underpinning this, and you go back and you take a look at who's been influencing the process. And it's been those who really believe that our objective must be far grander, and that is to redraw the political map of the Middle East," Wilson added.
This was the first time that Wilson had spoken out publicly against the administration's policies. It was two and a half weeks before the start of the Iraq war.
But it wasn't Wilson who Cheney was so upset about when he visited the CIA in March 2003.
During the same CNN segment in which Wilson was interviewed, former United Nations weapons inspector David Albright made similar comments about the rationale for the Iraq war and added that he believed UN weapons inspectors should be given more time to search the country for weapons of mass destruction.
The National Security Council and CIA officials said Cheney had visited CIA headquarters and asked several CIA officials to dig up dirt on Albright, and to put together a dossier that would discredit his work that could be distributed to the media.
The officials said a "binder" was sent to the Vice President's office that contained material that could be used by the White House to discredit Albright if he continued to comment on the administration's war plans. However, it's unclear whether Cheney or other White House officials used the information against Albright.
A week later, Wilson was interviewed on CNN again. This was the first time Wilson ridiculed the Bush administration's intelligence that claimed Iraq tried to purchase yellowcake uranium from Niger.
