(CNN) -- A U-Haul truck loaded with equipment for a Monday, September 3rd event featuring Vice President Joe Biden was stolen in Detroit Sunday, a spokesman for the U.S. Secret Service said.
"A U-Haul that we were utilizing was stolen at the Westin Hotel overnight," Ed Donovan told CNN.
Donovan would not specify what equipment was in the U-Haul at the time it was stolen, and added that the theft shouldn't affect the vice president's plans on Monday.
Biden is scheduled to speak at a Labor Day rally in downtown Detroit Monday and march in a parade organized by the Michigan AFL-CIO. Last year President Barack Obama spoke at the Motor City's Labor Day celebration.
