PORTLAND, Ore. (AP) — Protesters in Oregon’s largest city have clashed again with federal agents outside a U.S. Immigration and Customs Enforcement building that has become a new focus of the demonstrations that have gripped Portland for months. Portland police say people in a group of about 100 late Thursday and early Friday sprayed the building with graffiti, hurled rocks and bottles at agents and shined laser lights at them. The Oregonian/OregonLive reported that the agents set off smoke or tear gas and used crowd-control munitions in response. Police say three people were arrested. The protests have happened nightly since the police killing of George Floyd in Minneapolis.
