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 new Trump administration could put a stop to pending litigation on the abortion pill mifepristone and other federal abortion policies through changes at the Department of Health and Human Services, according to a top anti-abortion lawyer involved in several pending cases.

President Donald Trump issued executive orders late Friday reviving some of his first term’s anti-abortion policies, like restrictions on federal funding for family planning and some overseas health programs.

He overturned two orders issued by former President Joseph Biden that had burnished federal abortion protections. And he reinstated a longstanding Republican policy barring federal funds from going to organizations overseas that perform or promote abortions.

President Donald Trump delivered his Day One promise to the anti-abortion movement four days into his second term: He pardoned nearly two dozen anti-abortion activists convicted of federal offenses that included using physical force to block access to and invade abortion clinics,

In the background of his anti-immigration orders and attacks on civil rights, the president and his allies are advancing their anti-abortion agenda.
