With the eighth anniversary of the tragic events of September 11, 2001, new life was breathed into the fight to discover the "truth" about the events of that day. The movement is known as the 9/11 truther movement. Individuals and organizations have been working for years to force the government to form an independent investigating commission. A previous investigation was performed; however, the group believes many questions have been left unanswered. On September 11, 2001, over 3,000 people were killed in the World Trade Center buildings in New York City.

Members of the group, known as "Truthers", are comprised of individuals and organizations that question the government's explanation of the events of September 11, 2001. Members blame the U.S. government for planning or having advanced knowledge of the attacks. Truthers believe the government used the attacks as an excuse to launch wars in Afghanistan and Iraq. The attacks also gave the U.S. government a reason to enact several laws that aimed to curtail civil liberties. Members of the movement believe the main objective of the attacks was to ensure America's future supply of oil.
