The U.S. Department of Education said Tuesday it is investigating Denver Public Schools over allegations that a high school teacher required students of the same sex to kiss in front of a class. Denver schools spokesman Scott Pribble said the district put the teacher on administrative leave and completed an investigation after students raised concerns in March 2025. DPS did not say whether its investigation substantiated the specific allegation cited by the Education Department. Bethel School District said the vials were not authorized by school administrators and were immediately removed and turned over to the Pierce County Sheriff's Office. The Education Department tied the new investigations to National Parents’ Day on Sunday.
