- TaxpayersReduces risk that taxpayer dollars support research in jurisdictions with weaker welfare reporting.
CARGO Act of 2025
Read twice and referred to the Committee on Health, Education, Labor, and Pensions.
This bill amends the Public Health Service Act to prohibit the National Institutes of Health from funding any research activity or program that uses live animals unless that research takes place within the United States. "United States" is defined to include States, territories, and possessions. The bill is motivated by findings about historical NIH funding to foreign organizations and concerns about oversight and animal welfare.
Liberals stress global health collaboration harms; conservatives stress stopping taxpayer-funded overseas experiments
Relative to its intended legislative type, this bill is a straightforward substantive policy change that clearly states a prohibition on NIH support for live-animal research conducted outside the United States and cites supporting findings.

Who stands to gain, and who may push back.
These are examples from the analysis, not a ranked list of the most-affected groups.
- WorkersDisrupts international collaborations and multisite studies that rely on overseas animal work.
- Potential burdenCould slow preclinical research timelines by eliminating access to specialized foreign models or facilities.
- Potential burdenIncreases research costs because U.S. facilities generally have higher operating and compliance expenses.
Why the argument around this bill splits.
Liberals stress global health collaboration harms; conservatives stress stopping taxpayer-funded overseas experiments
Likely sympathetic to the animal welfare rationale but concerned about blunt impacts on global health research and equity.
Prefers stronger oversight, alternatives to animal use, and careful transition measures rather than an absolute ban.
Views the oversight concerns as legitimate but sees the ban as overly broad and possibly counterproductive.
Would favor targeted reforms, verification requirements, or conditional exceptions instead of an outright prohibition.
Likely supportive because it prevents U.S. taxpayer money funding animal research overseas and asserts national control.
Some concern exists about harming U.S. scientific competitiveness, but many conservatives favor restricting federal funding abroad.
