We told you yesterday about a county in Florida where thousands of students are isolating or quarantining because of COVID.
Now the Hillsborough County school board says it will impose a 30-day mask mandate for students and staff.
Parents there spoke out at a school board meeting.
"We are surrendering our children to a pandemic of sincere ignorance and conscience stupidity," said one parent.
The board's 5-2 vote to mandate masks came a week after classes started.
Now the decision could set up a clash with Florida Gov. Ron DeSantis who says mask mandates are illegal.
