White House spokesman Jay Carney said during a press briefing on Monday that a seizure played a role the weekend hit-and-run crash involving U.S. Commerce Secretary John Bryson. However, he stopped short of blaming the medical condition for the crash.

"The commerce secretary was alone. He had a seizure. He was involved in an accident," Carney said.  Pressed on whether the seizure caused the crash, though, Carney declined to say and instead referred reporters to the Commerce Department.
