Marco Antonio Mendoza-Cesar, a Venezuelan national, was detained by ICE agents during an operation at the Port of Astoria's Pier 1 on June 7, 2026. ICE conducted the operation on federally controlled port property without notifying Port of Astoria officials or local law enforcement. The operation raised concerns about whether it violated Oregon's sanctuary law, which prohibits state and local agencies from participating in immigration enforcement without a judicial warrant.
