Reproductive rights advocates sounded the alarm Friday after the Trump administration released a final draft of a rule critics have called an attack on women’s rights and dubbed a “domestic gag rule.”

The implications of the restrictive changes to Title X—on which over 4 million people rely—”are staggering,” said Dr. Leana Wen, president of the Planned Parenthood Federation of America and the Planned Parenthood Action Fund, adding that the move amounted to “an attack on poor women and people of color.”

The release (pdf) came from the Department of Health and Human Service’s Office of Population Affairs. It “would prohibit federally funded family planning clinics from being housed in the same location as abortion providers” and “bar taxpayer-funded family planning clinics from referring women for abortions,” as the Associated Press reports. The changes would affect not only (pdf) Planned Parenthood clinics, but numerous other health centers across the nation.

Given the president’s previous implementation and expansion of the so-called Mexico City Policy (aka the “global gag rule”), the International Women’s Health Coalition (IWHC) said the administration was bringing the “deadly global policy home.”

In her Twitter thread objecting to the proposal, Wen argued the new rule “compromises [doctors’] ethical obligation” and that the federal funding, apart from providing access to abortion, which is “standard medical healthcare” for women, also “helps people get testing for STDs, helps prevents cancer, and empowers people to make the best health choices for themselves.”
