Overview
- Rep. Nancy Mace posted this week that she would file the TRANS MICE Act to bar federal funds for research she described as altering an animal’s biological sex.
- X users and a platform Community Note corrected Mace’s language by explaining that 'transgenic' mice are genetically modified lab animals used in disease studies and are not 'transgender' animals.
- Mace responded by saying her concern was about 'federally funded transgender-related experiments on animals' and defended the bill after receiving criticism.
- Critics mocked the claim on social media and linked it to President Donald Trump’s earlier false statement that taxpayers were funding efforts to 'make mice transgender,' which fact‑checkers refuted.
- Transgenic mice are lab models altered to carry foreign DNA for research into conditions such as cancer and asthma, and the episode highlights how scientific terms can be politicized and used as symbolic messaging as Mace prepares to leave Congress next year.
