The Supreme Court starts 2022 with an ultra-rare Friday argument session over President Joe Biden’s vaccine policies as the country continues to struggle with Covid-19. The justices will hear back-to-back arguments Friday over the employer and healthcare-worker mandates, an unusual step for the sort of emergency litigation that the court generally decides with briefs alone. Cases and Controversies hosts Kimberly Robinson and Jordan Rubin give a sneak peek of the action and also preview the arguments coming up the week of Jan. 10, featuring disputes over Medicaid payments, immigrant detention, and whether tax courts can forgive late legal filings.
