The Trump administration is reversing a policy that required fingerprinting for all adults living in a household where a migrant child would live. Parents and other sponsors have said the fingerprinting rule had slowed placement of children in homes, in part because some members of the household were afraid to be fingerprinted.

Federal judges in California have challenged more of the Trump administration's "zero-tolerance" policy on illegal immigration. Their decision in Sept. 2018 to no longer accept pleas at initial appearances led to the dismissal of many cases because the government deported defendants before they could return to court. The judges' stance is another example of how the judiciary, in ways large and small, has put the brakes on some of the administration's efforts to curb immigration. (AP Photo/Felix Marquez, File)

Migrants traveling with children walk up a hill to a waiting U.S. Border Patrol agent just inside San Ysidro, Calif., after climbing over the border wall from Playas de Tijuana, Mexico, Monday, Dec. 3, 2018. Thousands of Central American migrants who traveled with recent caravans want to seek asylum in the United States but face a decision between crossing illegally or waiting months, because the U.S. government only processes a limited number of those cases a day at the San Ysidro border crossing.
