New Jersey Gov. Phil Murphy has warned residents that they risk being turned away from polling places if they don’t wear a face mask.

Murphy issued the advisory during a COVID-19 briefing on Wednesday, saying: "If you refuse to wear a mask, we’re not letting you in."

"It’s that simple," Murphy said in response to a question on mask policy. "You’ve got to wear a mask if you’re going into a store, going into a restaurant. You’ve got to wear one going to the Motor Vehicles Commission, wherever you’re going."

"If you’re indoors, you’ve got to wear a mask," he added.

The governor tweeted a "reminder" around the same time as his briefing, reiterating that Centers for Disease Control and Prevention (CDC) guidance only relaxes outdoor mask use, but that "masking-up remains mandatory indoors."

Murphy noted, however, that poll workers will not be required to be vaccinated: The state will only "strongly, strongly, strongly" encourage that they get the shot, he said.

Murphy's office did not return Fox New's request for comment. 

The state reportedly enforced the same stance at school board elections last week in six districts across the state, N.J. 1015 reported.

Polling stations reported no issues with the policy.

The policy was also in place last year during the presidential election, with few issues reported at the time.
