After a week of protests over federal immigration raids, about 200 Marines moved into Los Angeles on Friday to guard a federal building in the city while communities across the country prepped for what’s anticipated to be a nationwide wave of large-scale demonstrations against President Donald Trump’s polices this weekend.

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

The largest is expected to take place in Portland, where at least five separate demonstrations are planned in and outside of downtown. Two downtown events will happen on Naito Parkway. One will gather at the Salmon Street Springs and another will form at the Battleship Oregon Memorial in Tom McCall Waterfront Park.
