WATCH: White House reacts to SCOTUS ruling on vaccine mandates

The Supreme Court has dealt a major blow to the Biden administration, ending a White House requirement that employees at large businesses get a vaccine or test regularly and wear a mask on the job. The court's conservative majority concluded the administration overstepped its authority by seeking to impose the Occupational Safety and Health Administration's vaccine-or-test rule on U.S. businesses with at least 100 employees. At the same time, the court is allowing the administration to proceed with a vaccine mandate for most health care workers in the U.S., resulting in a mixed decision for the administration. Reacting to the ruling, Psaki hailed the decision allowing mandates for health care workers as "good news," saying the administration will continue to enforce it. On the OSHA ruling, Psaki said the White House will "continue to call on businesses to immediately join those those who have already stepped up, including one third of Fortune 100 companies, to institute vaccination requirements to protect their workers, customers and communities."
