Virginia Attorney General Jason Miyares filed a motion seeking to join a lawsuit against the Loudoun County School Board for defying Gov. Glenn Youngkin’s executive order allowing parents to opt-out of school mask mandates.

Miyares filed the motion Wednesday together with Youngkin and state superintendent of public instruction Jillian Balow, seeking to join a group of Loudoun County parents who had sued the school board for its refusal to allow parents to opt their children out of school mask mandates. The school district has threatened to suspend students who attempt to attend classes unmasked.
