U.S. Secret Service placed the White House on lockdown at around 1:15 p.m. Tuesday afternoon after a suspicious package was found near the North Lawn.

About an hour later, the Secret Service and Washington, D.C. police investigated the package and cleared the scene. The lockdown was lifted a short time later.

Construction work and landscaping on the North Lawn came to a halt and reporters were directed to hold in the James S. Brady briefing room.

President Trump is not in the building having just left Washington, D.C., for a rally in Arizona Tuesday night.

The Secret Service tweeted pedestrian traffic near the scene was restricted.
