Missouri’s attorney general has renewed a push to restrict access to the abortion pill mifepristone, arguing in a lawsuit filed this month that its availability hurt the state by decreasing teenage pregnancy.

Attorneys general from three states, including Kansas, are suing the FDA over recent changes to how abortion pills can be prescribed and received.

Republican-led states are restarting efforts to limit access to mifepristone, the primary drug used in medication abortions, in a bid to address what some experts saw as deficiencies in the case recently decided at the Supreme Court this past spring.
