WILMINGTON, Del. (AP) — Wilmington police say a 46-year-old driver believed to be drunk accidentally plowed into a parked SUV that was guarding President Joe Biden’s motorcade Sunday night while the president was leaving a visit to his campaign headquarters. The president and first lady Jill Biden were unharmed.

While Biden was walking from the campaign office to his waiting armored SUV, the sedan struck a U.S. Secret Service vehicle that was being used to seal off the area surrounding the headquarters for the president’s visit. The driver then tried to continue forward into the closed-off intersection, before Secret Service agents surrounded the vehicle with weapons drawn and instructed the driver to put his hands up.

Wilmington police said Monday their investigation determined the driver, a 46-year-old Wilmington man, accidentally struck the SUV and he was charged with drunk driving and inattentive driving.
