AP Explains: A look at rallies, recent tension in Portland

Portland, Oregon, Mayor Ted Wheeler speaks during a rally on Wednesday, Aug. 14, 2019. The mayor said anyone planning violence or espousing hatred at an upcoming weekend protest by right-wing groups in the liberal city "are not welcome here." Wheeler spoke with other city leaders ahead of the event Saturday, which is also expected to bring out anti-fascist protesters. Anticipating trouble, none of the city's nearly 1,000 police officers will have the day off Saturday.
