The White House and U.S. Capitol complex were briefly locked down Tuesday morning after an aircraft entered restricted airspace in the area.
Reporters at the White House were urged to stay inside, and access to the Capitol was restricted shortly before 9 a.m.
“The White House was locked down this morning due to a potential violation of the restricted airspace in the National Capital Region,” the Secret Service said in a statement.
Capitol Police said they were “tracking an aircraft that poses a potential threat to the Capitol Complex.”
The lockdown was lifted at the White House about 20 minutes after notification. Around the same time, people were reportedly allowed to resume entering Capitol buildings.
Congress is out of session this week for the Thanksgiving holiday. President Trump is set to leave the White House later Tuesday to travel to Florida, where he will hold a campaign rally and spend the holiday at his Mar-a-Lago estate.
