PORTLAND, Ore. (KOIN) — Supporters of President Trump gathered in Salem Saturday as part of a nationwide “Stop the Steal,” rejecting the outcome of the 2020 Presidential Election. The demonstration went on for most of the afternoon, but as the evening approached, tensions between pro-Trump demonstrators and counter-protesters rose.

Salem Police declared an unlawful assembly around 5 p.m. and ordered the crowd to disperse, according to Zane Sparling of the Portland Tribune. Authorities closed the street in front of the Oregon Capitol building to traffic and diverted cars away.

Oregon State Police reported four arrests were made during the rally.
