Anti-abortion groups are pressing the Trump Justice Department and Food and Drug Administration to quickly reverse Biden administration policies on abortion pills and impose a clampdown, including the use of a 19th-century anti-obscenity law to block the mailing of the drugs.

The anti-abortion movement has launched a pressure campaign urging President Donald Trump’s administration to take steps toward a nationwide ban on medication abortion, the method used in nearly two-thirds of all abortions nationwide.

The president reinstated a policy blocking U.S. aid to foreign organizations that use funds for abortion. He also overturned two Biden executive orders, contending they violated the law barring federal funding for abortion.

President Donald Trump signed an executive action reinstating the so-called Mexico City Policy, delivering an early and expected victory to opponents of abortion rights who helped fuel his return to power.
