Former Commerce Secretary John Bryson's blood tested positive for Ambien after Bryson was involved in two separate hit and run incidents (including one in which he crashed into the same car twice) in Los Angeles in early June. Prosecutors declined to press charges, stating that the amount of Ambien was consistent with the "low end of therapeutic levels," which makes it impossible for criminologists to prove that Bryson was under the influence.

U.S. Commerce Secretary John Bryson was found unconscious behind the wheel of a vehicle that struck two cars in the San Gabriel Valley on Saturday.
