U.S. Secretary of State Mike Pompeo announced the expansion of restrictions for foreign aid to organizations that provide abortion-related services or advocacy on Wednesday.

“We will refuse to provide assistance to foreign NGOs that give financial support to other foreign groups in the global abortion industry,” Pompeo said at a press conference in Washington D.C. The new restrictions strengthen the so-called “Mexico City Policy,” also known as the “Global Gag Rule.”

The provision prohibits U.S. aid to overseas NGOs which offer any services related to abortion even if those services are not paid for with U.S. funds, including referrals or counseling, by closing loopholes organizations could use to circumvent the policy’s original restrictions.
