A car has crashed into a vehicle near President Joe Biden's motorcade in Delaware, according to a Reuters eyewitness.
The US President and First Lady Jill Biden are both said to be "safe".
A Bloomberg reporter posted to X, formerly Twitter, and said the car crashed into an SUV that had closed a street while Biden attended a campaign event.
Reuters reports Biden and his wife had just left his campaign headquarters on Monday (NZ time) after having a meal of pasta with tomato sauce with members of his re-election team.
Security officers surrounded the vehicle after it stopped and the Bidens returned safely to their home in Wilmington.
