The Secret Service said the seal spent the night at the side of Interstate 76 when it fell from the side of Obama's limo Thursday night and police and Secret Service agents were unable to locate it that night, CNN reported Monday.
Secret Service spokesman Ed Donovan said a Philadelphia police officer who was a part of the Thursday motorcade found the seal at the side of the road Friday.
"It happens periodically," Donovan said of the symbol falling from the car. "They're only magnetic. They're not put on any special way."
