The lockdown on the White House has been lifted without incident after an unattended package near the North Fence was investigated.
The United States Secret Service placed the White House on lockdown at around 1:15pm on Tuesday afternoon (local time).
The U.S. Secret Service tweeted "@SecretService and @DCPoliceDept have cleared the unattended package near the north fence line of the @WhiteHouse Complex".
The North Lawn was evacuated and reporters and construction workers in the area were sent into the West Wing.
The Secret Service says the package was determined to be harmless about an hour later. The owner has not been located.
President Trump was not in the building at the time, as he had just left for a rally in Arizona.
