Three Pittsburgh, Pennsylvania mothers filed a lawsuit last week to stop a first grade teacher from instructing their kids about transgender transitioning and other gender identity topics.

Fox News reported that the lawsuit seeks a "court order to stop the gender-related instruction or offer parents the chance to excuse their children from it" at Jefferson Elementary School in the Mount Lebanon School District.

The plaintiffs Carmilla Tatel, Stacy Dunn and Gretchen Melton name first-grade teacher Megan Williams in their suit as having violated the Constitution, state law, and district policy by teaching gender ideology in the elementary school class.
