Scholars for 9/11 Truth & Justice (STJ) formed in January 2007 and is a self-described "group of scholars and supporters endeavoring to address the unanswered questions of the September 11, 2001 attack through scientific research and public education". The group is composed of more than 900 members, including Richard Gage, Steven E. Jones, Jim Hoffman, David Ray Griffin, and former Congressman Daniel Hamburg. Most members support the conspiracy theory that the World Trade Center Towers and the third skyscraper, WTC 7, were destroyed through explosive demolition.
