A number of people have gathered in Lafayette Park just outside White House, where the white nationalist rally will take place.
The "Still Here, Still Strong" rally started at 12 p.m. in Freedom Plaza.
Police in riot gear showed up at the Vienna Metro Station where white nationalists, including rally organizer Jason Kessler , took the Metro to Foggy Bottom before their rally at 5:30 p.m.
At least one person was arrested there.
Lafayette Park has been split into sections. The southwest quadrant is the designated area for white nationalists and nearly the entire northern half is permitted for counterprotesters. The area designated for the white nationalists is now closed to the public. The two groups will be separated by barriers and distance; two sidewalks and a grassy area are part of the designated buffer zone.
According to National Park Service permits, Unite the Right expects around 400 demonstrators. Five other permits show that nearly 10 times that number could show up on the side of the counterprotesters.
