Florida Gov. Ron DeSantis said Supreme Court justices John Roberts and Brian Kavanaugh lacked “backbone” for not striking down the Biden administration’s health care worker vaccine mandate.

In two decisions Thursday, the nation’s top court struck down the Biden administration’s COVID-19 vaccine mandate for large businesses, but upheld its mandate for most healthcare workers.

Roberts and Kavanaugh sided with the court’s liberal justices, upholding the the health care-worker vaccine mandate, five to four.

“Honestly, Roberts and Kavanaugh did not have a backbone on that decision. That’s just the bottom line,” DeSantis said on an episode of the right-leaning podcast Ruthless.
