U.S. Commerce Secretary John Bryson suffered a seizure, a department spokeswoman said in a statement on Monday after police in California announced he was being investigated for several hit-and-run car crashes.
Bryson, Obama's top trade official, was hospitalized in California but has returned to Washington, Commerce Department spokeswoman Jennifer Friedman said in a statement. The investigation into the crashes is ongoing, she added.
Earlier on Monday, police in Southern California said Bryson was found unconscious behind the wheel of his Lexus after crashing three times into two other cars. At least one crash is being investigated as a felony hit-and-run.
The San Gabriel Police Department, in a statement released early Monday, said a preliminary investigation indicates Bryson caused the first crash when his Lexus rear-ended a Buick in the city on Saturday at about 5:05 p.m. He hit it again when leaving the scene.
The second crash took place about five minutes later in nearby Rosemead, California, when Bryson allegedly hit a Honda Accord, according to the statement, which was issued along with the Los Angeles County Sheriff's Department.
Bryson was treated at the scene of the second crash by paramedics and then admitted to a local hospital for non-lethal injuries, police said. Passengers in the other cars had no major injuries.
