Waukesha Alderman Don Paul Browne tells CNN he was participating in today's Christmas parade, but said he was out of the parade before the incident occurred.
“This is so sad and senseless," he said. "There was so much joy and holiday spirit in the air before all this happened."
He urged people to "keep our victims, families and our community in your thoughts and prayers.”
More than 20 people were injured Sunday when an SUV plowed into Waukesha's holiday parade.
