The Trump Administration formally came out Friday in favor of cutting off federal family planning money to organizations that perform abortions or make referrals for them.

The rule change affects Title X, the $260 million federal program which underwrites the costs of contraception, reproductive health services and STD screening for low-income and uninsured patients.

The fundamental premise of this Title X change is as simple as it is controversial: The administration believes abortion is not "family planning" and the two do not belong in the same place or conversation.

NPR broke out the details further, saying it "would require facilities receiving federal family planning funds to be physically separate from those that perform abortion; would eliminate the requirement that women with unintended pregnancies be counseled on their full range of reproductive options; and would ban abortion referrals."

The White House says this change fulfills Trump's “promise to continue to improve women’s health and ensure that federal funds are not used to fund the abortion industry in violation of the law.” Critics call it a "gag rule" that prevents caregivers from giving patients full information and makes good on Trump's vow to defund Planned Parenthood.

In a conversation with Glamour this week, Sen. Elizabeth Warren slammed the Title X proposal as bad policy that could endanger women.

“Forcing doctors to keep information from patients about their health options is dangerous and just plain wrong,” the Massachusetts Democrat said.

What Trump is pursuing isn't new: He's bringing home the essence of the so-called “Mexico City Policy,” which cuts off federal funding to worldwide health groups that perform abortions or even provide information about them.

The proposal now on the table could have an outsized effect on Planned Parenthood, which offers a variety of reproductive and wellness services in addition to abortion. According to Kaiser Health News, "Planned Parenthood affiliates account for about 13 percent of total Title X sites but serve an estimated 40 percent of its patients."

Federal law has long prohibited the use of public money to subsidize abortion procedures. But Warren, who was among many lawmakers who signed a letter protesting the Title X changes, says “there's a lot more on the line as well."

The Title X rule change “demands that multi-service providers not put a woman's best interest first — and that if they do, they will lose federal funding for the full array of healthcare services,” Warren said. “That’s shocking.”

"Accessible contraceptives, services to help women prevent unplanned pregnancies [and] care for children after they're born are all under attack by the Republicans," she added.

Warren also called the fight a matter of equity. “Threatening to cut back on basic health care services disproportionately hits communities of color, the uninsured and low-income women," she said.
