Biden’s Schools Bid Pits CDC Science Against Union Clout Bloomberg 2/10/2021 Josh Wingrove (Bloomberg) -- President Joe Biden’s push to reopen U.S. schools is running headlong into his pledge to support teachers, who are demanding more coronavirus testing, vaccinations and other safety measures before returning to classrooms. The president has pledged to follow the science as he nudges schools toward welcoming more students back to class, while also enjoying broad support from teachers and their unions. First Lady Jill Biden, a teacher herself, welcomed the heads of the two top teachers unions to the White House on the administration’s first full day in office.
