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.
