PORTLAND, Ore. (AP) — The actions of federal law enforcement officers at protests in Oregon’s largest city are raising the prospect of a constitutional crisis. It’s one that could escalate as weeks of demonstrations find renewed focus in clashes with federal agents. Protests have wracked Portland for 52 days following George Floyd’s death in Minneapolis. The Trump administration dispatched the officers from federal agencies against the wishes of state and local officials. The state has sued over the agents’ actions. Constitutional law experts call those actions “unprecedented” and a “red flag.” Trump says he plans to send federal agents to other cities, too.
