The existence of Project 112 (along with the related Project SHAD) was categorically denied by the military until May 2000, when a
CBS Evening News investigative report produced dramatic revelations about the tests. This report caused the
Department of Defense and the
Department of Veterans Affairs to launch an extensive investigation of the experiments, and reveal to the affected personnel their exposure to toxins. Revelations concerning Project SHAD were first exposed by independent producer and investigative journalist
Eric Longabardi. Longabardi's six-year investigation into the still-secret program began in early 1994. It ultimately resulted in a series of his investigative reports, which were broadcast on the
CBS Evening News in May 2000. After the broadcast of these exclusive reports, the Pentagon and Veteran's Administration opened their own ongoing investigations into the long classified program. In 2002, Congressional hearings on Project SHAD, in both the Senate and House, further shed media attention on the program. In 2002, the US sailors exposed in the testing filed a federal class action lawsuit. Additional actions, including a multi-year medical study, were conducted by
National Academy of Sciences/Institute of Medicine to assess the potential medical harm caused to the thousands of unwitting US Navy sailors, civilians, and others exposed in the secret testing. The results of that study were released in May 2007. Because most participants involved with Project 112 and SHAD were unaware of any tests, no effort was made to ensure the
informed consent of the military personnel. The US Department of Defense (DoD) conducted testing of agents in other countries that was considered too unethical to perform in the United States. Until 1998, the Department of Defense stated officially that Project SHAD did not exist. Because the DoD refused to acknowledge the program, surviving test subjects were unable to obtain disability payments for health issues related to the project. US Representative
Mike Thompson said of the program and the DoD's effort to conceal it, "They told me – they said, but don't worry about it, we only used simulants. And my first thought was, well, you've lied to these guys for 40 years, you've lied to me for a couple of years. It would be a real leap of faith for me to believe that now you're telling me the truth." The Department of Veterans Affairs commenced a three-year study comparing known SHAD-affected veterans to veterans of similar ages not involved in any way with SHAD or Project 112. The study cost approximately US$3 million, and results are being compiled for future release. DoD has committed to providing the VA with information it needs to settle benefits claims as quickly and efficiently as possible and to evaluate and treat veterans involved in those tests. This required analyzing historical documents recording the planning and execution of Project 112/SHAD tests. == Criticisms after disclosure of CBW testing ==
