U.S. Attorney General Merrick Garland said Thursday that the Justice Department "strongly disagrees" with a court ruling tightening restrictions on the abortion pill mifepristone, and would appeal it to the Supreme Court.

"We will be seeking emergency relief from the Supreme Court to defend the FDA's scientific judgment and protect Americans' access to safe and effective reproductive care," he said, referring to the Food and Drug Administration.
