Idaho, Kansas and Missouri can proceed with their push against abortion pill mifepristone, a judge in Texas ruled Thursday. The big picture: The Republican-led states are seeking to roll back federal rules on the drug to make it harder for people to access the abortion pill through telehealth prescriptions.

A federal judge in Texas is allowing three other states to pursue a challenge seeking to restrict access to the abortion pill mifepristone nationwide.

The states of Idaho, Kansas and Missouri made the request in U.S. District Court in Amarillo, Texas. The only judge based there is Matthew Kacsmaryk, a nominee of former President Donald Trump who previously ruled in favor of a challenge to the pill’s approval.
