The wife of Democratic presidential candidate Barack Obama escaped injury Tuesday when the vehicle that was carrying her to a campaign event in Iowa collided with a motorcyclist.
The motorcyclist was injured and taken to the hospital, said Katie McCormick Lelyveld, a spokeswoman for Michelle Obama.
None of the campaign staff in the vehicle with Mrs. Obama were hurt.
The vehicle was hit by the motorcycle as it attempted a left turn just south of Hampton, where Michelle Obama was due at a rally.
She later told the crowd the event would be rescheduled.
