Protesters across the U.S. are calling for a nationwide strike on Friday to oppose the Trump administration’s immigration crackdown in Minneapolis. The demonstrations calling for “no work, no school, no shopping” come almost a week after intensive care nurse Alex Pretti was killed while recording Border Patrol officers with his cellphone. Multiple businesses announced they would be closed during the “blackout,” while some schools canceled classes in anticipation of mass absences. Some students are planning walkouts, while others plan to gather in churches, courthouses and city centers in solidarity.
