Federal authorities are expected to set up a large fence across the perimeter of the White House ahead of the election.
A law enforcement source told NBC News that crews would build a “non-scalable” fence to secure the White House complex and nearby Lafayette Square.
About 250 National Guardsmen have been put on standby as well.
CNN confirmed the report, adding that it will be the same type of fence as was set up during protests in Washington DC during the summer.
Concerns about civil unrest:
Businesses in the DC area and other major cities have also boarded up their windows amid concerns over potential civil unrest following the election.
"It is widely believed that there will be civil unrest after the November election regardless of who wins," D.C. Police Chief Peter Newsham warned lawmakers in October. "It is also believed that there is a strong chance of unrest when Washington, D.C., hosts the inauguration in January."
Trump planning election party:
Trump, who initially planned to host an election night party at his DC hotel, is now expected to host up to 400 people at the White House, according to The New York Times.
The party will be held in the East Room despite the last major event -- Amy Coney Barrett’s nomination announcement -- apparently leading to numerous coronavirus infections, including Trump, first lady Melania Trump, and their son Barron.
Polls show Trump trailing nationally by more than eight points and trailing in key battleground states.
