Rep. Nancy Mace Introduces Bill To End Taxpayer-Funded Radical Animal Experiments

(Washington, D.C., August 1, 2025) — Today, Congresswoman Nancy Mace (SC-01) introduced the Transgender Research on Animals Now Stops and Money for Ideological Cruelty Eliminated Act, also known as the TRANS MICE Act, to put an end to the use of taxpayer dollars for radical transgender-related experiments on animals.

Rep. Mace has led the charge in exposing the reckless waste of taxpayer dollars on these experiments and is fighting to shut them down for good.

Earlier this year, she chaired a House Oversight hearing titled “Transgender Lab Rats and Poisoned Puppies: Oversight of Taxpayer-Funded Animal Cruelty,” where it was revealed at least $241 million in federal funds had been spent on gender-transition experiments involving animals.

“Americans are rightfully tired of seeing their tax dollars spent on wasteful experiments disguised as research while advancing a political agenda,” said Congresswoman Nancy Mace. “This legislation brings accountability, ends taxpayer-funded cruelty, and ensures science serves the public, not ideology. It protects both animals and the integrity of public trust. We commend the work White Coat Waste Project has done to shine a light on this issue and help drive meaningful reform.”

Senior Vice President at government watchdog White Coat Waste Project, Justin Goodman, provided the following statement: 

"Thanks to the outstanding leadership of Rep. Nancy Mace and White Coat Waste’s viral investigations, the Trump Administration has slashed spending on wasteful experiments that subject lab animals to invasive surgeries and hormone therapies to crudely mimic gender transitions in kids and adults—only to later wound, shock and inject the animals with viruses, vaccines and overdoses of sex-party drugs,” said Justin Goodman. These Trump cuts have already saved thousands of lab animals and millions of tax dollars, but we’ve uncovered dozens of active grants that also have funneled federal dollars to disturbing transgender animal tests. Taxpayers shouldn’t ever be forced to foot the bill for wasteful and disturbing transgender animal tests—and Rep. Mace’s commonsense TRANS MICE Act will ensure they won’t be."

The TRANS MICE Act bans the use of any federal funds to conduct, support, or fund research which seeks to alter an animal’s biological sex through drugs, hormones, surgeries, or other interventions, unless the species naturally undergoes sex changes or possesses both male and female reproductive organs.

This bill supports President Trump’s stance, who called out these experiments as a clear example of government waste, fraud, and abuse during his address to Congress earlier this year.
