In May of 2003, David Petraeus cooperated with Bush crony Stephen Cambone to push the narrative that the military had found biological weapons trailers.
"The suspected mobile biological agent production lab found on 9 May in our area was found by one of our infantry units during operations at the al-Kindi Rocket and Missile Research and Development Center," Major General David Petraeus said May 13 during a briefing from Mosul. "Our own chemical section looked at the trailer and confirmed it as a trailer that was very close to identical to the first trailer that was found by Special Forces southeast of here last week."
Petraeus said he spoke with experts May 13, and they have a "reasonable degree of certainty that this is in fact a mobile biological agent production trailer."
