Overseas nonprofits working in maternal health could have funding jeopardized by the expanded Mexico City Policy.

WASHINGTON — The State Department on Monday officially announced a broad expansion of the Mexico City Policy, a regulation put in place by every Republican president since Ronald Reagan that prevents foreign nongovernmental organizations that perform or promote abortions from receiving American dollars.

Typically, the Mexico City Policy has only impacted funds specifically earmarked for family planning programs. Under the new policy, however, organizations that perform other health-related work and happen to support abortions — for example, a foreign NGO that does sexual health education to prevent the spread of HIV and also informs women that abortion is legal in the country — could see the whole of their US health funding disappear.
