Illinois Gov. JB Pritzker announced that Abbott Labs will provide Chicago public schools 350,000 COVID-19 tests amid the omicron surge and the impasse between the teacher's unions and the school district to return to classrooms.
"I am committed to seeing our kids and teachers safely in classrooms ASAP. I want to thank the CEO of Abbott, Robert Ford, who was committed to helping get kids back to school by providing rapid antigen tests, along with the team at SHIELD Illinois," Pritzker said in a statement Saturday.
"Together, they turned over every stone ... I appreciate their hard work, along with that of my staff who worked nonstop behind the scene to get this done," he said.
Chicago Public Schools canceled classes last week amid negotiations over remote learning and COVID-19 safety measures.
City leadership, including Mayor Lori Lightfoot, had asked teachers to continue in-classroom instruction, but 88% of the Chicago Teachers Union's leadership and 73% of its members voted last week in favor of remote education.
