CHANTILLY, Virginia — A group of roughly 70 students at Chantilly High School in northern Virginia marched out of class and off school grounds without adult supervision to protest Republican Gov. Glenn Youngkin’s new policies on transgender students.

Shortly after 2 p.m. local time, the group of students, many waving or wearing gay and transgender pride flags, congregated outside the school building for a brief rally before parading off the school grounds and down the sidewalk into a residential area.
