Gov. Phil Murphy had strong words for those who are opposed to his COVID-19 mandates.

A group of people carrying signs opposed to mandatory vaccinations showed up at the governor’s rental assistance bill signing on Wednesday.

Murphy became fed up with their message.

“You folks back there have lost their minds. You have lost your minds. You are the ultimate knuckleheads and because of what you’re saying and standing for, people are losing their lives. And you have to know that,” Murphy said. “Look in the mirror. Look in the mirror.”

Supporters of the governor and his mandates went on to cheer his name.

Murphy recently unveiled a new vaccine mandate for workers in hospitals, long-term care facilities and prisons.
