Gwen Walz, the wife of Democratic vice presidential nominee Tim Walz, on Wednesday slammed GOP presidential nominee Donald Trump’s boast about being the “father of IVF” as not just “creepy” but “downright nuts.”

Trump made the wild claim during a Fox News town hall taped Tuesday in Georgia.

Walz tackled Trump’s comment at a campaign event in the same state.

The former president had “tried to rewrite his terrible record on reproductive freedom,” Walz said, adding she “can hardly believe” his “father of IVF” brag.

“That’s what he said. That’s a direct quote: the ‘father of IVF.’ I would say more like the father of Georgia’s abortion ban,” she continued.

“Now, I’m a longtime teacher and in my classroom we believe in facts, so here are a few,” said Walz, who with her husband turned to fertility treatment for help when they struggled to have children.

Walz then noted Trump’s role in overturning Roe v. Wade, which has led to extreme abortion bans in multiple states, and how Trump’s platform “threatens IVF nationwide.”

After each fact, the audience joined her in saying, “That’s a fact.”
