D.C. police cleared an unattended book bag that earlier prompted the Secret Service to evacuate the north lawn of the White House Tuesday afternoon.
The unattended book bag was found along the north fence, according to D.C. Fire and EMS, which assisted police at the scene.
All reporters and construction workers were told to go inside immediately, NBC News national correspondent Peter Alexander tweeted. They have been allowed to return to their posts on the lawn.
Pedestrian traffic along Pennsylvania Avenue NW between 15th and 17th streets near Lafayette Square was restricted while the bag was investigated.
The president was not at the White House.
