Joseph Oakman and fellow Proud Boys plant a flag in Tom McCall Waterfront Park during an "End Domestic Terrorism" rally in Portland, Ore., on Saturday, Aug. 17, 2019. Portland Mayor Ted Wheeler said the situation was "potentially dangerous and volatile" but as of early afternoon most of the right-wing groups had left the area via a downtown bridge and police used officers on bikes and in riot gear to keep black clad, helmet and mask-wearing anti-fascist protesters — known as antifa — from following them.
