Bryson was issued a citation at an area hospital where he received treatment, said Lt. Ariel Duran of the San Gabriel Police Department. Authorities must still decide whether to formally file any charges.  Bryson voluntarily took a breathalyzer test that detected no alcohol use, the Los Angeles Sheriff's Department confirmed Monday. Results from a separate blood alcohol test were pending, Duran said.  A police statement Sunday said the investigation was in "its preliminary stages," and that there was no indication of alcohol or drugs playing a role.  "Secretary Bryson was involved in a traffic accident in Los Angeles over the weekend," said a statement by Commerce Director of Public Affairs Jennifer Friedman. "He suffered a seizure. He was taken to the hospital for examination and remained overnight for observation. He was released and has returned to Washington. The investigation is ongoing."  At the White House earlier Monday, Carney said Bryson has "health-related issues that played a role" in the weekend incident.  Carney provided no further details, noting the Commerce Department statement about Bryson suffering a seizure.  "He was alone, he had a seizure, he was involved in" the accidents, Carney said in explaining the difficulty in determining exactly what happened.  In announcing Bryson's medical leave of absence Monday night, Carney said in a statement that Bryson had notified the White House of the leave and, "The President's thoughts are with Secretary Bryson and his family during this time."  Neither Carney's statement nor his remarks earlier indicated whether Obama had spoken directly with Bryson since the accidents.  According to a Commerce official, Bryson was on personal time with no security detail when the accidents occurred and was driving his own vehicle. The official, who spoke to CNN on condition of not being identified, said Bryson was given medication to treat the seizure.
