REHOBOTH BEACH, Delaware -- President Joe Biden and first lady Jill Biden were moved from their Rehoboth Beach, Delaware, home as a precautionary measure on Saturday afternoon after a small private plane entered restricted airspace, a White House official said.
"A small private plane entered restricted airspace, all indications are by mistake, and precautionary measures were taken," an official told reporters Saturday. "There was no threat to the President or his family."
A White House official later added that the President and first lady were moved from their Rehoboth Beach home but are now back at their residence.
The Bidens are spending the weekend in Rehoboth Beach, in part to celebrate the first lady's birthday, which was Friday.
The US Secret Service confirmed in a later statement that the small plane had entered the restricted airspace near the Bidens' beach house by mistake.
According to the statement from the Secret Service, shortly before 1 p.m., a privately owned aircraft entered the restricted airspace over Rehoboth, Delaware after "mistakenly entering a secured area."
The aircraft was immediately escorted out of the restricted airspace, the Secret Service said.
"Preliminary investigation reveals the pilot was not on the proper radio channel, was not following the NOTAMS (Notice to Airmen) that had been filed and was not following published flight guidance," the Secret Service said. "The United States Secret Service will be interviewing the pilot."
Additionally, a USSS official told reporters on background, "Precautionary security measures were taken but there was no significant threat to the protectee."
