This is a clip of George W. Bush saying "Islam is Peace" during a speech he gave on September 17, 2001.
This clip comes from a longer video of the entire speech which was originally published on the White House web site at this address: http://www.whitehouse.gov/news/releases/2001/09/20010917-11.html (This address stopped working after the Obama administration redesigned the web site.)
I have set the audio of GWB saying "Islam is Peace" to music, and am posting this clip as evidence that he really said it.
