Scuffles broke out shortly after 6 pm local time as Antifa protesters pelted marchers from the conservative group with eggs, water bottles and firecrackers as the marchers spilled out into downtown Portland for their legally permitted march in support of a conservative Republican candidate for the U.S. Senate. The march followed an afternoon rally at Terry Schrunk Federal Plaza, Reuters reported.
Officers seized weapons like utility knives, clubs and chemical sprays from Antifa protesters as they gathered nearby for their counter-rally.
Portland police eventually made four arrests during the demonstrations - though they said none of them were related to the day's events. Four others had to be taken to the hospital after being struck by projectiles.
