A New Hampshire track and field coach said he was fired for opposing his school’s face mask mandate.

“I will not put kids on the track and tell them to run any races while wearing masks,” former Pembroke Academy coach Bradley Keyes said in a letter to the school’s athletic director. “I will not stand up in front of the kids and lie to them and tell them that these masks are doing anything worthwhile out in an open field with wind blowing and the sun shining.”
