Conservative appeals court to hear challenge on abortion pill accessibility.

The Biden administration will argue in front of the 5th U.S. Circuit Court of Appeals that mifepristone, a widely used abortion pill, is safe and that a lower court overstepped its authority by ruling that the FDA's decades-old approval was invalid. The case marks the highest-stakes legal battle on abortion since the Supreme Court overturned Roe v. Wade last summer. Should the administration lose, access to a common abortion medication would be limited, and the entire U.S. drug approval system could be upended.
