Laurie McGinley and Amy Goldstein report in the Washington Post:

President Trump, in reinstating a rule first instituted by President Reagan, gave foreign nonprofits a stark choice: Stop providing abortions, or any information about abortions, or lose valuable dollars from the United States, the biggest global funder of family-planning services.

Advocacy groups that oppose the rule are also claiming that the rule forbids grant recipients from sharing any information about abortion.

This is incorrect. A USAID handbook from 2007, when the rule was in place, characterized its effect as follows:

No funds made available under this award will be used to finance, support, or be attributed to the following activities: (i) procurement or distribution of equipment intended to be used for the purpose of inducing abortions as a method of family planning; (ii) special fees or incentives to any person to coerce or motivate them to have abortions; (iii) payments to persons to perform abortions or to solicit persons to undergo abortions; (iv) information, education, training, or communication programs that seek to promote abortion as a method of family planning; and (v) lobbying for or against abortion. The term “motivate”, as it relates to family planning assistance, shall not be construed to prohibit the provision, consistent with local law, of information or counseling about all pregnancy options (emphasis added).

Whether recipients of federal dollars should be able to provide abortion referrals in foreign countries where abortions are legal is a debatable question. But the Mexico City policy does not forbid them from doing so.
