The decision to reinstate the Los Angeles County indoor mask mandate, regardless of vaccination status, has seen mixed reviews, particularly by Villanueva.
In a statement, Villanueva claimed that the new mandate to force even the vaccinated to wear a mask is "not backed by science" and contradicts federal guidelines.
"Forcing the vaccinated and those who already contracted COVID-19 to wear masks indoors is not backed by science and contradicts the U.S. Centers for Disease Control and Prevention (CDC) guidelines," Villanueva wrote.
He explained that the county's Department of Public Health has the "authority" to enforce the order. However, he stated that the "underfunded" and "defunded" sheriff's department under his watch "will not expend our limited resources."
"We encourage the DPH to work collaboratively with the Board of Supervisors and law enforcement to establish mandates that are both achievable and supported by science," Villanueva added.
The order that mandates masks for residents "regardless of vaccination status" was implemented after a rise in positive Chinese coronavirus cases in the county and will take effect Saturday at 11:59 p.m., according to L.A. County Health Officer Dr. Muntu Davis.
"We're not where we need to be for the millions at risk of infection here in Los Angeles County, and waiting to do something will be too late given what we're seeing now," Davis said Thursday, according to the Los Angeles Times.
