A Commerce Department memo revealed Monday night that Secretary John Bryson would take a medical leave of absence effective immediately following car crashes he was involved in Sunday. Earlier in the day, a spokesperson said Bryson had suffered a seizure in connection with the two accidents that occurred in Los Angeles. He had been treated and released from a Los Angeles hospital. "I notified President Obama this evening that effective immediately I am taking a medical leave of absence so that I can focus all of my attention on resolving the health issues that arose over the weekend," Bryson said in the memo. It was unclear whether the seizure caused the two accidents or was a result of them. Bryson was cited for a felony hit and run by the Los Angeles County Sheriff’s Department, which said that one of the two traffic accidents was caused by the 68-year-old Bryson.
