Nancy Mace Introduces the “TRANS MICE” Act to Ban Federal Funding for Sex-Altering Animal Research
6/21/2026, 10:49:49 PM
Core Event
Rep. Nancy Mace (R-SC) introduced the Transgender Research on Animals Now Stops and Money for Ideological Cruelty Eliminated Act (“TRANS MICE Act”) on June 19 2026, banning federal funding for studies that alter an animal’s sex.
Background & Context
The bill follows former President Donald Trump’s 2025 claim that taxpayers funded “making mice transgender,” a claim later debunked, and comes amid a surge of anti-transgender legislation in Congress.
Key Figures & Groups
Primary actors include Rep. Mace, the White Coat Waste Project supporting the bill, scientific researchers using transgenic mice for disease studies, and fact-checkers such as Molly Jong-Fast and Laura Barrón-López.
Official Statements & Responses
Mace called the act a safeguard against “ideological cruelty.” The White Coat Waste Project said it ensures science serves the public. PBS noted the research targets basic gene function, not gender-affirming care.
Criticism & Opposition
Scientists argue transgenic mice are vital for cancer and asthma research. Commentators on X point out the conflation of “transgenic” with “transgender,” labeling the bill a scientific misunderstanding.
Data & Statistics
Transgenic mice are routinely used in cancer and asthma studies. The White Coat Waste Project claims recent cuts saved “thousands of lab animals and millions of tax dollars.”
Implications & Impact
If enacted, the act would prohibit federal funding for such research, potentially affecting studies that rely on sex-alteration models. It also signals a legislative focus on cultural issues over scientific priorities.
Conflicting Reports & Gaps
Mace’s claim of federally funded “transgender-related” animal experiments conflicts with community notes identifying the work as transgenic research. Trump’s similar claim was also debunked; no evidence of sex-changing studies exists.
Verbatim Quotes
- “This is not science. This is ideological cruelty paid for by the American taxpayers.” — Nancy Mace, Rep. (R-SC)
- “The idea that scientists are making mice transgender is false,” — Laura Barrón-López, journalist (PBS)
- “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,” — Molly Jong-Fast, journalist
- “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,” — Justin Goodman, White Coat Waste Project
What’s Next
The TRANS MICE Act now faces House committee review. Its fate will hinge on broader partisan battles over federal research funding and concurrent anti-transgender legislation.
