Protests against the Trump administration, which are set to continue this weekend after a week of uprising that spread from Los Angeles across the country, have energized a portion of the left-wing base that has been despondent since President Trump’s election.

Denver police arrested 18 individuals during an "ICE Out!" immigration protest, with tensions over ICE policies sparking demonstrations and officials responding to potential conflict.

Millions of people turned out for "No Kings" protests nationwide on Saturday that were largely peaceful though there were some arrests and police had to disperse unruly crowds, including in Georgia and Los Angeles.

Organizers of the “No Kings” demonstrations said millions had marched in hundreds of events. In Oregon, tens of thousands of people gathered in downtown Portland for two large protests -- one that began in Tom McCall Waterfront Park and the other at the Oregon Convention Center.
