The Trump administration is expanding a ban on U.S. aid to foreign groups that promote or provide abortions to include those who support others who do, Secretary of State Mike Pompeo announced Tuesday.

“We will enforce a strict prohibition on back-door funding schemes and end runs around our policy,” Pompeo said. “American taxpayer dollars will not be used to underwrite abortions.”

The Mexico City policy, named for the city where it was first announced, requires foreign non-governmental organizations to certify that they do not perform or promote abortion as a part of family planning programs in order to receive U.S. funds.

Pompeo said the ban will now extend to those foreign NGOs that provide financial support to other groups who provide abortion services or counseling.

Trump reinstated and expanded the Mexico City policy after taking office, applying it beyond family planning organizations to global health groups, including those focus on HIV, malaria, tuberculosis, maternal and child health, and nutrition. The policy was first instituted under the Reagan administration and was rescinded and reinstated by subsequent Democratic and Republican administrations, respectively.

Critics argue the policy, which they call a “global gag rule” over its application to all family planning services, threatens the health of the world’s most vulnerable populations, including women in developing nations with limited access to care.

Sen. Jeanne Shaheen, D-N.H., who leads a bi-partisan group of senators pushing a permanent revocation of the rule, urged congressional leadership Tuesday to immediately bring their legislation to a vote.

“This administration’s obsession with attacking women’s reproductive health is egregious and dangerous,” Shaheen said in response to Pompeo’s announcement. “Further expanding the global gag rule puts international organizations in an impossible position: provide women the full scope of reproductive health care services or deny critical funding that saves lives. That is unconscionable.”

Pompeo dismissed criticism that the policy could lead to more pregnancies and abortions in rural areas as “just wrong.”

The U.S. currently provides $9 billion in aid to global health programs, and Pompeo said assistance would remain at the same level.

“This administration has shown that we can continue to meet our critical global health goals, including providing health care for women, while refusing to subsidize the killing of unborn babies,” he said.

Pompeo also announced that the United States will cut funding to the Organization of American States for abortion-related activities forbidden under the Siljander amendment, a federal law that bans the use of U.S. funds to lobby for abortion.

“The institutions of the OAS should be focused on addressing crises in Cuba, Nicaragua, and in Venezuela, not on advancing the pro-abortion cause,” said Pompeo, who said the decrease in funding to the organization would be equal to “the estimated U.S. share of possible OAS expenditures on these abortion related activities.”

The State Department said Tuesday afternoon that $210,000 would be withheld from the assessed U.S. contribution to the OAS Inter-American Commission on Human Rights for fiscal year 2019 “in light of concerns regarding certain of their activities related to abortion."
