U.S. fighter jets on Saturday “scrambled” to intercept a civilian aircraft north of President Joe Biden’s residence in Wilmington, Del.

The civilian aircraft entered restricted airspace shortly after 2 p.m., according to Anthony Guglielmi, chief of communications for the United States Secret Service. The aircraft landed safely at a nearby airport.

“As a precaution, assets were scrambled to intercept and the civilian aircraft safely landed at a nearby airport. There were no impacts to the protectee’s movements as a result of this incident and agents from the United States Secret Service are investigating in coordination with the Federal Aviation Administration,” Guglielmi said.

The president is in Wilmington this weekend, and his movements weren’t affected. He attended church Saturday evening after the incident.
