New security fencing went up around the White House, U.S. Capitol and Vice President Harris’s residence in Washington, D.C. as authorities prepare for Election Day in the event there may be political unrest in the coming days.

The Secret Service constructed eight-foot-high metal fences around the White House and Treasury Department complex and the adjacent parts of Lafayette Square, the Naval Observatory and Harris’s house in D.C., The Washington Post reported.

At the Capitol, previously used temporary bicycle-rack barriers stated “Police Line: Do not cross,” surrounding the perimeter.

The Secret Service also have plans for physical security measures outside of the West Palm Beach, Fla. convention center where former President Trump will host an event on Election Night, the outlet reported.

Harris will spend Election Night at her alma mater, Howard University, in D.C. The Washington, D.C. Police Department said in a post Sunday that there will be street closures, no parking zones and transit detours for the surrounding area.

Officials have said there are no current threats to Washington ahead of the election, but locals are bracing for upset supporters and the fencing and plywood are reminders of the 2020 presidential election and the Jan. 6 attack on the Capitol.

The Hill has reached out to the Secret Service and the U.S. Capitol Police for more information about their preparation.
