(Portland, OR) -- Protesters' occupation of Portland's "Red House on Mississippi" enters day four today. KOIN-TV reports that demonstrators have moved their barricades down Mississippi Avenue, expanding their perimeter. The demonstrators are trying to prevent the eviction of a Black and Indigenous family who has lived at the home since the 1950s. The family says they're the victim of a predatory loan company. Mayor Ted Wheeler says the city is working with several law enforcement agencies and bureaus to resolve the standoff.
