Federal authorities expected to erect ‘non-scalable’ fence around White House

Federal authorities are expected to put back into place a “non-scalable” fence around the entire perimeter of the White House on Monday as law enforcement and other agencies prepare for possible protests surrounding the election, a source with knowledge of the matter confirmed to CNN.

The fence, the same type that was put up during protests this summer, will encompass the Ellipse and Lafayette Square. It will go down 15th Street to Constitution Avenue and then over to 17th Street. The fence will then run up to H Street and across by Lafayette, and then come down 15th Street, the source said.

NBC News was first to report the new fencing. The Secret Service did not respond to a request for comment.

The extra layer of security marks the most high-profile example to date of authorities preparing for unrest following this year’s election, particularly if there is no clear winner come November 4.

As CNN previously reported, the immediate perimeters around the White House have already been largely blocked off to the public this year for a range of reasons, from construction on the White House gate, to protests and looting that occurred in downtown Washington in the wake of the police killing of George Floyd in Minneapolis in May.

Lafayette Park, across the street from the north side of the White House and a popular protest gathering spot, had also largely been fenced-in since police aggressively moved in on protesters alongside it in July.

Washington, DC, Metro Police Chief Peter Newsham warned the District’s City Council last month there was wide expectation of some type of civil unrest following the election. And many businesses in the downtown DC area in the proximity of the White House have boarded up doors and windows in the last couple of days in anticipation of possible protests.

During this past summer, some businesses saw their windows smashed and other property damaged by protesters.

But DC Metro police have been preparing its officers for well over a year, as it does ahead of every general election, ensuring that they are prepared to handle everything from civil disturbance to crowd control to potential disruptions to metro transit, Patrick Burke, executive director of the Washington, DC, Police Foundation, previously told CNN.

Police have also been working with intelligence officials to ensure the security of Washington, DC’s airspace in the event of an attack from above, Burke added, as they routinely do when preparing for moments of heightened anxiety.

“If there’s no winner, you will see significant deployments of officers at all levels across the capital,” said Burke. “Officers will get cancellations of days off, extensions of shifts and full deployments of officers across the city.”
