U.S. Commerce Secretary John Bryson, a cofounder of the Natural Resources Defense Council and onetime Morrison & Foerster partner, faces the possibility of felony hit-and-run charges after being involved in a pair of car accidents over the weekend in Southern California.

A seizure of some kind may have been to blame for the fender benders, according to a Commerce Department spokeswoman who confirmed to the Los Angeles Times that Bryson was involved in the accidents. The 68-year-old Bryson cooperated with detectives, who do not believe that alcohol and drugs played a part in the accidents.
