The US Capitol is being evacuated and the White House is on lockdown amid reports that fighter jets have been scrambled to respond to an airspace violation in Washington, local media reports said on Tuesday.
A video uploaded by Cheddar's J.D. Durkin shows a Secret Service officer standing guard outside of the press room.
Roads around the White House have been closed to traffic, a Sputnik correspondent said.
According to MSNBC, fighter jets have been scrambled in Washington after an aircraft failed to respond to air traffic controllers.
The lockdown began shortly after 9 am and was lifted some 20 minutes later, NBC News reported.
