Washington (CNN) - U.S. Secretary of Commerce John Bryson, who is under investigation for possible felony hit-and-run after allegedly causing two weekend car accidents in California, suffered a seizure, a Commerce Department spokeswoman said Monday.
Police said Bryson was found unconscious at the wheel of his car on Saturday after the two accidents.
Bryson, 68, was issued a citation at an area hospital where he received treatment for minor injuries, said Lt. Ariel Duran of the San Gabriel Police Department. Authorities must still decide whether to formally file any charges.
"The investigation is in its preliminary stages. At this point in time, there is no indication that alcohol or drugs played a role in the collisions," police said in a statement Sunday.
A preliminary alcohol screening of Bryson was negative, Duran said. Results from a blood alcohol test were pending, he said.
