(CBS News) Commerce Secretary John Bryson, who was cited in a felony hit-and-run case in southern California over the weekend, suffered a seizure, the Commerce Department announced Monday.
"Secretary Bryson was involved in a traffic accident in Los Angeles over the weekend," spokeswoman Jennifer Friedman said in a statement. "He suffered a seizure."
A Commerce official, speaking on background, told CBS News that Bryson was given medication to treat the seizure.
Only minor injuries were reported in the two accidents in San Gabriel and Rosemead, Calif., outside Los Angeles Saturday around 5 p.m. PT. Bryson was found unconscious at the scene of the second accident.
The secretary was hospitalized overnight for observation, according to Friedman. He was in California to give a commencement address and has since returned to Washington.
Bryson was driving his own vehicle without a security detail, according to the Commerce official.
On "CBS This Morning" Monday, before the Commerce Department's announcement, David Axelrod, senior adviser to President Obama's re-election campaign, didn't provide further details.
"This news broke overnight, so I don't really have anything to contribute to that. Obviously it's concerning, but, you know, I'm not going to comment because I don't know any of the details," he said.
