it. A July 2012 article in the AIA's magazine criticized Gage for continuing to intimate that he has an association with the organization, and claimed that there were no architects at an Architects and Engineers for 9/11 Truth screening held in an AIA boardroom. RIBA released a statement saying the perception that it endorses events held in its buildings is "regrettable", and said it would review policy on "private hire" of its buildings. Anthony Summers and Robbyn Swan offer scathing criticism of many of the above theories in The Eleventh Day, their 2011 investigation of the attacks. U.S. representative Peter T. King, chairmen of the House Homeland Security Committee, said 9/11 conspiracy theorists "trivialize" the "most tragic event to affect the United States" and that "[p]eople making these claims are disgraceful, and they should be ashamed of themselves". The hosts of "The Skeptics' Guide to the Universe" (the "SGU") have spoken repeatedly about the "absurdity of 9/11 conspiracy theories". In addition to critiquing the theories using the same or similar arguments as the above, the "SGU" hosts say that, like most conspiracy theories, this one collapses under its own weight and contradicts itself. In order for the 9/11 conspiracy theories to be correct, the U.S. government would not only have to orchestrate the claimed false flag operation regarding the airplanes that crashed into the World Trade Center, but they would also have to orchestrate a superfluous controlled demolition and cover their tracks so flawlessly that it becomes indistinguishable to physicists from the "official story", yet the plan would have to be flawed enough so that "losers in their mothers' basement" will discover the conspiracy. In politics Former Canadian Liberal Party leader Stéphane Dion forced a candidate from Winnipeg, Lesley Hughes, to terminate her campaign after earlier writings from Hughes surfaced in which Hughes wrote that U.S., German, Russian and Israeli intelligence officials knew about the 9/11 attacks in advance. Peter Kent, Deputy Editor of Global Television Network News and a Conservative Party candidate in the 2008 Canadian election, had earlier called for Hughes's resignation, saying that the 9/11 Truth movement is "one of Canada's most notorious hatemongering fringe movements" composed of "conspiracy theorists who are notorious for holding anti-Semitic views." On June 16, 2009, Hughes sued Kent, the Canadian Jewish Congress, the B'nai B'rith of Canada and four senior members of the two organizations, alleging the antisemitic allegations were untrue
