• A man drove his SUV through a Christmas parade in Waukesha, Wisconsin, last Sunday.

• Wisconsin's senators – a Democrat and a Republican – asked people not to politicize the tragedy.

• The crash left six people dead.

Wisconsin's two senators, Democrat Tammy Baldwin and Republican Ron Johnson, issued a joint statement asking people outside the state not to politicize last weekend's Waukesha tragedy.

"It has come to our attention that outside individuals or groups may attempt to exploit the tragedy that occurred last Sunday in Waukesha for their own political purposes. As the US Senators representing Wisconsin, one from each political party, we are asking anyone considering such action to cease and desist," Baldwin and Johnson wrote.

On Sunday, a red SUV drove through barricades and smashed into crowds of people at a Christmas parade in Waukesha, which is part of the Milwaukee metropolitan area.
