The gag rule, also known as the Mexico City policy, blocks international family planning assistance through the U.S. Agency for International Development to any groups or programs that provide or even mention abortions to women, or speak out about abortion laws in their own countries. It was last implemented by President George W. Bush and then was repealed by President Barack Obama.

Trump’s plan, called Protecting Life in Global Health Assistance, goes much further than that. The policy applies the anti-abortion rule to $8.8 billion in global health funding furnished by the State Department, USAID and the Department of Defense, instead of only $600 million in family planning funding. This means that a clinic receiving U.S. assistance for HIV or Zika relief will lose all that money if it so much as gives pregnant women information about safe abortion care.
