A federal judge on Friday halted federal regulators' approval of the abortion pill mifepristone while a legal challenge proceeds, partially granting a request by anti-abortion groups and dealing another setback to abortion rights in the United States.

The 67-page ruling by U.S. District Judge Matthew Kacsmaryk in Amarillo, Texas, will not take effect for one week, in order to give the Biden administration a chance to file an emergency appeal.

A White House official said they are reviewing the abortion ruling.
