Walter began a series of advertisements about the September 11, 2001 attacks in October 2004, which included full page ads in the "New York Times" and "Wall Street Journal", and 30 second cable television spots on CNN, Fox News, and ESPN. They implied that no plane flew into The Pentagon, and that 7 World Trade Center was brought down by internal explosives. They called for a new investigation into what happened on September 11, and referred viewers to the website reopen911.org. In conjunction with the campaign, Walter sponsored an October 2004 Zogby poll, which found that 66% of New York City residents wanted a fuller investigation of the events of September 11.
