Federal authorities are reportedly\u0026nbsp;planning to erect a \u0022non-scalable\u0022 fence around the entire perimeter of the White House on Monday as law enforcement officials, including 250 national guardsmen put on standby, prepare for possible protests in the aftermath of Election Day.\u0026nbsp;NBC News White House Correspondent Geoff Bennett was the first to report on the latest White House fence construction plans.\u0026nbsp;CNN confirmed the news, citing an unnamed source \u0022with knowledge of the matter.\u0022\u0026nbsp;\u0022The White House on lockdown,\u0022 Bennett tweeted on Sunday night, just hours after it was reported that President Donald Trump is planning to prematurely claim victory if he has a lead Tuesday night, as the Republican Party bolsters its\u0026nbsp;attempt to further delegitimize mail-in ballots counted after November 3.\u0026nbsp;The White House on lockdown: A federal law enforcement source tells NBC that beginning tomorrow, crews will build a “non-scalable” fence to secure the WH complex, Ellipse and Lafayette Square.250 National Guardsmen have been put on standby, reporting to Metro Police officials.— Geoff Bennett (@GeoffRBennett) November 2, 2020According to CNN, the \u0022non-scalable\u0022 fencing being set up this week is the same type that was put into place during this summer\u0026#039;s protests against racism and police violence that erupted in the wake of the killing of George Floyd by Minneapolis officers in May.\u0026nbsp;The source said that the fortification will \u0022encompass 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 to 15th Street.\u0022Many observers—regardless of the outcomes—anticipate post-election turbulence this year. \u0022The extra layer of security,\u0022\u0026nbsp;CNN reported, \u0022marks the most high-profile example to date of authorities preparing for unrest following this year\u0026#039;s election, especially if there is no clear winner come November 4.\u0022Expectations of and preparations for potential political violence are unusually high this year, driven in large part by Trump\u0026#039;s dangerous encouragement of armed \u0022poll watchers\u0022 as well as other cases—such as the harassment of a Biden campaign bus by reckless, pro-Trump motorists this weekend—in which the president has incited and/or condoned violence and intimidation.\u0022Four years after pledging to make America great,\u0022 political columnist Frida Ghitis noted on social media, \u0022Trump has to turn the White House into a fortress to protect himself from the people.\u0022Four years after pledging to make America great, Trump has to turn the White House into a fortress to protect himself from the people.

Which will be on lockdown, starting tomorrow, with National guardsmen deployed. They are building additional fencing. There is a bunker.
