White nationalists and anti-racism protesters will face off just metres from the White House on Sunday as both mark the one-year anniversary of violent clashes in Charlottesville.
Both groups have been given permission to demonstrate in separate sections of Lafayette Square, a shady park that looks onto the back of the US president’s residence.
Attendees of "Unite the Right 2", a follow-up to the controversial far-Right protest last year, have been told to bring Confederate flags, wear body cameras and expect to be provoked.
A collective of counter-protest groups will stage a rally earlier in the day before congregating at the park and have vowed to drown out the white nationalists’ message.
Secret service officials will join officers from Washington DC’s police force and the National Park Service to ensure there is no repeat of the violent clashes this time last year.
The incident led to one of the most controversial moments of Donald Trump’s presidency as he blamed “both sides” for the violence – the white nationalists and anti-racism protesters.
The comment triggered a wave of condemnation from politicians and campaigners, including senior Republicans, over Mr Trump’s failure to call out racism.
On Saturday Mr Trump issued a pre-emptive call for peace, tweeting: “The riots in Charlottesville a year ago resulted in senseless death and division.
“We must come together as a nation. I condemn all types of racism and acts of violence. Peace to ALL Americans!”
Mr Trump was accused of being a "racist" and using the n-word this week by a former White House aide and Apprentice star Omarosa Manigault Newman in a new book.
The white nationalist protest will instead take place in Washington DC from 5pm to 7.30pm and will see attendees march through the city to Lafayette Square.
Counter-protesters will hold a rally earlier in the day before also heading to the park. Between three and four thousand people in total are expected to attend, for both sides.
Makia Green, a 26-year-old core organiser for Black Lives Matter DC, told The Telegraph that she hoped the group’s counter-protest would send a powerful message.
She said: “I want people to know that the power of black communities across the world is going to be stronger and vaster than the white supremacist hate that we’ve been experiencing.”
