This seems like a potential security breach. If they got close enough to steal the equipment, that means they were close enough to tamper with it. If the equipment was going to be in close proximity to Biden, his podium for example, the danger is obvious.
"A U-Haul truck loaded with equipment for a Monday 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."
