The Trump administration posted a final rule Friday that would require family planning clinics to be housed in separate buildings from abortion clinics, a move that would cut off Planned Parenthood from some federal funding.

The rule applies to a $286 million-a-year grant, known as Title X, that pays for birth control, testing of sexually transmitted diseases, and cancer screenings for 4 million low-income people. It requires the “physical and financial” separation of family planning services and abortion.
