A fight over abortion pills at the Supreme Court this week could have sweeping consequences for all Americans’ access to mifepristone, even those who live in blue states.

Abortion will be back in court Tuesday, when the same justices who overturned Roe v. Wade will hear arguments about whether federal regulators overstepped their authority by loosening restrictions to make mifepristone easier to access.

Mifepristone, which is sold both under the brand name Mifeprex and as a generic drug, is commonly used with one other drug during medication abortions. The stakes of the case were made clear this week when new data showed more than 60 percent of all abortions last year were done through medication.
