Hundreds of students from Iowa's largest school district are marching out of their classrooms on Tuesday, Sept. 30, in protest of Superintendent Ian Roberts' arrest by U.S. Immigration and Customs Enforcement last week. Walk outs are scheduled from 10:30 a.m. to 3 p.m. at all five high schools and Central Campus. Students are expected to march to the Iowa Capitol after school ends. #Iowa #Iowacheck #iowafyp #IanRoberts #News #politics #protest
