The white nationalist who organized the deadly “Unite the Right” rally in Charlottesville, Virginia, last summer got a permit Thursday to stage another protest on Sunday in Washington, DC, to mark the first anniversary of the mayhem.

Jason Kessler’s rally permit was approved by the National Park Service, which also approved a permit for a counter-protest the same day — setting up another possible confrontation between the white nationalists and counter-protesters, some of them violent.

Kessler, who dubbed this year’s event “Unite the Right 2,” filed paperwork with the Park Service in May for a permit allowing 400 people to demonstrate in Lafayette Park, just across from the White House grounds, “to protest civil rights abuse in Charlottesville Va/white civil rights rally.”

Meanwhile, Virginia Gov. Ralph Northam and the city of Charlottesville declared a state of emergency ahead of the anniversary of the initial Unite the Right rally.

Heather Heyer, 32, was killed when she was struck by a car driven by a white nationalist that had rammed a crowd of counter-protesters.

Two Virginia state troopers also were killed that weekend when their helicopter crashed in woods nearby.

Charlottesville cops came under intense scrutiny a year ago for not intervening in the clashes between the torch-carrying racists and violent anti-fascist counter-protesters after video showed officers standing by and watching as people were beaten.

Scores of peaceful demonstrators who got caught in the middle were also injured.

President Trump later said there were “many fine people” among the white nationalists and blamed the violence “on both sides” — sparking outrage for appearing to offer support to the organizers of the protest.
