Washington (CNN) – U.S. Secretary of Commerce John Bryson, who is under investigation for possible felony hit-and-run after allegedly causing two car accidents in California, suffered a seizure, a Commerce Department spokeswoman said Monday.

Bryson was issued a citation at an area hospital after sustaining minor injuries in the Saturday accidents, said Lt. Ariel Duran of the San Gabriel Police Department. Authorities must still decide whether to formally file any charges.
