On 9/22/11 PRG petitioned the President to formally acknowledge an extraterrestrial presence engaging the human race. The White House response on 11/4/11 from the Office of Science and Technology Policy stated, "The U.S. government has no evidence any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race. In addition, there is no credible information to suggest that any evidence is being hidden from the public's eye."
There are scores of government/agency/political witnesses of rank and station prepared to testify under oath before congressional committees now about the evidence the White House states doesn't exist. See: www.citizenhearing.org
