WASHINGTON — Scott Lloyd’s unadorned job title betrays little hint of the power he has over the pregnant teenagers in his custody.

As director of the Office of Refugee Resettlement, he oversees the assistance program for the tens of thousands of refugees who still seek shelter in the United States, even with the Trump administration’s crackdown. But as the government official who is also responsible for the care of young, undocumented immigrants who enter the United States without their parents, he spends much of his time trying to stop those who want an abortion.

He has instructed his staff to give him a spreadsheet each week that tells him about any unaccompanied minors who have asked for one and how far along they are in their pregnancy. In at least one case he directed staff to read to one girl a description of what happens during an abortion. And when there’s a need for counseling, Mr. Lloyd’s office calls on someone from its list of preferred “life affirming” pregnancy resource centers.

Last fall Mr. Lloyd’s refusal to let a 17-year-old in Texas leave the shelter where she was living to get an abortion drew an admonishment from a federal judge who said she was “astounded” the government had been so insistent on keeping someone from obtaining a constitutionally protected procedure. Last week another judge barred him from trying to prevent any girl in his care from getting an abortion, but government lawyers have asked for a stay and plan to appeal.
