Rep. Nancy Mace Mocked for Bill Targeting 'Transgender Mice,' Which Aren't Real

South Carolina Rep. Nancy Mace is facing an onslaught of mockery after unveiling a bill to halt the supposed federal funding of “transgender mice.”

Mace, 48, announced the “TRANS MICE Act” on X Thursday, writing, “Animals should not be used for radical transgender experiments. This is not science. This is ideological cruelty paid for by the American taxpayers.”

Her post included an image of a mouse touching a human hand and the words: “NO TRANS MICE.”

“Our TRANS MICE Act ends it. No federal funds may be used to conduct, support, or fund research aimed at altering an animal’s biological sex,” Mace wrote. “No hormones. No surgeries. No taxpayer dollars spent mutilating animals in the name of transgender ideology.”

However, her post was quickly amended with a community note suggesting she misunderstood the research surrounding “trans mice,” which refers to transgenic mice — not transgender mice.

“‘Trans mice’ refers to transgenic mice, not transgender mice. Transgenic mice are defined as mice that have incorporated foreign DNA into their genome, allowing for the study of gene function and disease mechanisms, particularly in cancer research,” the community note read.

However, Mace pushed back on the fact check, insisting that she wasn’t talking about transgenic mice but “federally funded transgender-related experiments on animals.”

“This post is not about transgenic mice. It is about federally funded transgender-related experiments on animals,” she wrote. “The bill is called the Transgender Research on Animals Now Stops and Money for Ideological Cruelty Eliminated Act, also known as the TRANS MICE Act.”

While Mace stood behind her “trans mice” claims, the Internet had a field day correcting the South Carolina Republican — and roasting her ridiculous claims.

“Transgenic mice are laboratory animals that have had foreign DNA, such as a human gene or a specific genetic marker, artificially inserted into their genome. They are used for scientific testing,” journalist Molly Jong-Fast explained.

Political strategist Mike Nellis chimed in, writing, “The dumbest member of Congress, which is really saying something.”

Another X user added: “This soon to be former member of Congress does not understand that the studies refer to TRANSGENIC mice. Not turning mice transgender.”

“As someone who works with transgenic mouse models for cancer research, this is objectively one of the funniest things I’ve seen a real life politician post,” another X user wrote.
