Bush clearly lost the feed through his earpiece at 1:23 in this video, as captured by Veredictum. Bush spoke to reporters briefly at Camp David on 8/17/06 after a Federal judge in Detroit ruled Bush's warrantless wiretapping program unconstitutional and was asked about that ruling.

"I made my position clear about this war on terror.
I uh...
And uh... by the way, the enemy made their position clear, yet again, when they...
when... wwwwww... when... when umm... we were able to um... stop 'em, see."

Try to make sense of Bush's words: "The enemy made their position clear when we were able to stop 'em." It's impossible to make sense of them.

Obviously Bush never composed that sentence in his own mind. It only came out of his mouth because it was fed to him through an earpiece that failed.
