On July 7, 2025, a large-scale immigration enforcement operation took place at MacArthur Park in Los Angeles, a neighborhood with a substantial immigrant population. Approximately 90 members of the California National Guard were deployed to support immigration officers during the operation. The National Guard troops, accompanied by over a dozen military vehicles including Humvees, provided protection to heavily armed federal immigration agents. The operation involved agents on foot, horseback, and in armored vehicles, and lasted for about an hour. Defense officials confirmed that all National Guard troops involved were activated for this mission. The coordinated effort by federal officers and National Guard personnel aimed to carry out a raid in the park, underscoring the federal government's enforcement activities in the area.
