The 2017 Charlottesville rally, which drew white supremacists and neo-Nazis, was originally meant to protest the planned removal of a statue depicting Confederate General Robert E. Lee that still stands.
A student rally has been planned this weekend in Charlottesville to reclaim the campus square where the white supremacists marched a year ago wielding tiki torches.
Heather Heyer, a 32-year-old legal assistant, was struck and killed when a white supremacist slammed his vehicle into a crowd of counterprotesters.
But just a day later, Trump said there was "blame on both sides" for the violence in Virginia, pointing to anti-fascists who came "with clubs in their hands".
He then condemned all types of racism and acts of violence.
Mitt Romney, the Republican presidential nominee in 2012, now running for the US Senate from Utah, said in an essay published at the weekend that he disagreed with Trump's declaration that many "good people" had taken part on the white nationalist side of the Charlottesville event.
He said the president's call for peace and rhetoric condemning racism was "hollow". Some Republican lawmakers also pushed back, although initial statements by House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell didn't mention Trump by name.
"He has not gone far enough", Cummings said on ABC's "This Week". "He's got to address the - the people who are spouting racist-type comments and do racial, racist-type acts".
The mother of Heather Heyer, who died previous year when a white nationalist slammed his vehicle into counter-protesters in Charlottesville, has urged people to stay peaceful as Washington DC readies itself for Unite the Right 2.
In Washington on Saturday evening, almost two dozen police officers patrolled Lafayette Square, where members of the Washington chapter of Black Lives Matter were sprinkled through the park, seemingly standing on guard.
Several counterprotesters gathered near the Washington suburban metro station of Vienna, Virginia, where some white nationalists were expected to board trains to take them into the city.
"This event on Sunday will be that which allows the First Amendment to occur because our beat, our daily responsibilities on the National Mall is our nation's civic stage", said Unite States Park Police Chief Robert MacLean.
Police used vehicles and traffic cones to seal off the station's parking lot, where about 40 officers in ballistic vests were also deployed.
"Last year was a whole different story".
"We all have a responsibility to stand up to hate", Bro said this week.
With hundreds of police maintaining a tight security perimeter around a 15-block downtown area, Charlottesville's normally bustling business district was relatively quiet on Saturday. No cars were permitted in the central business area, and pedestrians had to pass through security checkpoints before they could enter.
The most intense moments occurred in the evening at the University of Virginia campus at the "Rally for Justice", where a group of some 200 Antifa activists shouted at riot police lines, "Black Lives Matter!" and "No Nazis, No KKK, No Fascist USA!".
The organizer of last year's rally, Jason Kessler, had vowed to hold a rally in a park near the White House on August 12 after Charlottesville denied him a permit.
The result, however, was a day largely devoid of conflict.
The preventative measures comes one year on from the harrowing violence that gripped the city one year ago.
