White House lockdown lifted after airspace violation
North American Aerospace Defense Command (NORAD) confirmed it "tasked aircraft to respond" after a plane reportedly entered restricted airspace. It followed up by saying its jets "are on site and responding," but noted the plane is not currently considered hostile.
"Senior interagency officials are monitoring the situation on a national event conference call," NORAD said.
The lockdowns at the federal legislature and executive mansion were lifted after about 30 minutes.
