WASHINGTON (Sputnik) — Staff members were permitted to re-enter the building one hour after the evacuation, the official said.
“The building is now open,” House Press Gallery Assistant Superintendent Ric Andersen said.
“An audible fire alarm sounded from the kitchen of the Capitol Visitor Center was the reason for the evacuation.”
Then, visitors were cleared for re-entry shortly after, he added.
Lawmakers were not in session during the evacuation as they are on recess, according to local media.
Capitol police temporarily closed the streets surrounding the Congress until the fire alarm check was completed.
