Antifa protesters in Portland clashed with authorities Wednesday as they gathered to voice dissatisfaction with President Joe Biden, forcing officers to retreat and taking at least one police bicycle, authorities said.

A crowd of up to 150 people gathered at Revolution Hall around 2 p.m. local time and marched to the headquarters of the Democratic Party of Oregon, Portland police Sgt. Kevin Allen said. The so-called J20 protest was a demonstration against Biden and law enforcement.
