(Portland, OR) -- The labor union that represents federal ICE officials is planning to sue the City of Portland. The National ICE Council filed the notice of intent to sue yesterday. They allege that Mayor Wheeler was wrong to order Portland police to stand down when protesters were blocking a federal building. The blockade lasted for several days before being shut down in late June. The ICE union says police didn't respond to some of their calls for service, which they believe violates their civil rights.
