Ahead of Election Day, D.C. is bracing for what could be a tumultuous time. Fencing was reinforced outside the White House in Lafayette Square Sunday night, and there was a similar scene outside the vice president’s residence, the Naval Observatory.

As millions of Americans prepare to decide the next president of the United States, extra security measures have been installed around D.C. in anticipation of Election Day.

Security fencing is going up around the White House, U.S. Capitol and Vice President Harris' residence in Washington, D.C. as authorities brace for possible unrest on or after Election Day. Why it matters: The security precautions in the nation's capital are the latest indication that the government views the culmination of the election as a potential powder keg.
