Children on the Frontlines

Hardline migration and asylum policies in the United States and Australia in 2018 hit turbulence when their effects on the most vulnerable—young children—provoked widespread public revulsion and prompted a retreat, at least temporarily.

Pushback to the Resistance: Criminalization of Humanitarian Actors Aiding Migrants Rises

As industrialized countries are adopting harder-edge immigration and asylum policies to deal with real and perceived crises, humanitarian actors have sought to blunt the effects of those policies by launching rescue missions at sea, rendering direct aid to migrants in need, and offering legal assistance.

Sessions: The Trump Administration’s Once-Indispensable Man on Immigration

In less than two years as Attorney General, Jeff Sessions oversaw wide-reaching changes to the U.S. immigration system. Even as the zero-tolerance policy, fights with "sanctuary" cities, and DACA termination might be more visible, Sessions' enduring legacy may be his muscular use of a little-noted authority, which he wielded to significantly reshape immigration and asylum policy by referring immigration cases to himself.
