Gwen Walz, wife of Democratic vice presidential nominee Tim Walz, lambasted the Republican running mate, JD Vance, at a rally Friday in Manassas, Virginia.

And to make sure the crowd knew she was serious, she did it in her “teacher glasses.”

The moment happened while Walz, the Minnesota governor and Kamala Harris’ running mate, was talking about a recently resurfaced comment by Vance criticizing Randi Weingarten, president of the American Federation of Teachers union, for trying to “brainwash” children while not having “a single child” of her own (she is a stepmother to two kids).

Considering the Walzes struggled with fertility issues before having two children, who are now in their late teens, she didn’t take too kindly to the Ohio senator’s hint that people who haven’t given birth to children shouldn’t be teachers.

And she let him have it.

“JD Vance said he was ‘really disturbed’ by teachers who don’t have biological children,” Gwen Walz said before mentioning her own personal story.

“For a long time, Tim and I were teachers who struggled with infertility. We were only able to start a family because of fertility treatments. We do not take kindly to folks like JD Vance telling us when or how to start our families,” she emphasized.

She then paused to put on a pair of glasses.

“So let me use my teacher voice. Mr. Vance, how about you mind your own business?”

Many people were impressed by Walz’s takedown and the teacher glasses she put on before delivering it.
