Federal prosecutors in Arizona charged 374 individuals across two immigration enforcement operations in late February and early March 2026. The first operation, conducted February 28 through March 6, resulted in 177 charges including 124 for unauthorized re-entry, 35 for unauthorized entry, and 18 for human smuggling, with three men specifically charged in connection with a Phoenix-based smuggling operation that transported undocumented migrants. A second operation from March 7-13 yielded 197 additional charges comprising 132 unauthorized re-entry cases, 59 unauthorized entry cases, and 6 smuggling cases. The operations involved multiple federal agencies and led to the discovery of 19 undocumented migrants in a Phoenix apartment.
