COULTER, Iowa (CNN) - Democratic presidential candidate John Edwards was about 45 minutes late to his first event Saturday but was soon forgiven when the crowd found out he'd witnessed a car accident and was assisting at the scene.
"We had a little mishap on the way down," Edwards said. "Everybody was fine though. It just slowed us down a little bit."
The former North Carolina senator's motorcade was headed south on Interstate 35 on its way to Coulter, Iowa, when Edwards said a tire came from across the median.
"[The tire] hit a car...very hard. Knocked it off the road, and we stopped and basically just took care of the people until the highway patrol got there."
Edwards said it was a preacher and his wife in the car on their way to Kansas City.
The campaign said Edwards provided his information to authorities in case he is needed to answer any questions.
As of Saturday night no police report had been made public.
