(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.
