(AP) — The Biden administration is increasing federal support for COVID-19 testing for schools in a bid to keep them open amid the omicron surge. The White House said Wednesday the administration is making a dedicated stream of 5 million rapid tests and 5 million lab-based PCR tests available to schools starting this month. The goal is to ease supply shortages and promote the safe reopening of schools. The White House says states can request the tests immediately and the tests will be available for use by the end of the month. The initiative comes after Chicago public schools closed for days amid an impasse between teachers and officials over reopening policies.
