(Portland, OR) -- A panel of the 9th Circuit Court of Appeals has paused an order by a federal judge in Portland that stopped ICE officers from using tear gas outside of their building in South Portland. The Department of Homeland Security argued it is authorized to do what is appropriate and necessary to diffuse violence against officers. The plaintiffs in the suit were the ACLU and residents of a nearby apartment complex. Oral arguments will be held April 7th.
