Detention of Migrant Families. The White House is considering restarting the detention of migrant families caught crossing the U.S. Mexico border four current and former U.S. officials told Reuters which would reverse a move to end the practice. President Biden has turned to increasingly restrictive measures as his administration prepares for the end of Title 42, which has allowed border authorities to swiftly expel migrants. The Biden administration is considering reviving the practice of detaining migrant families who cross the border illegally — the same policy the president shut down over the past two years because he wanted a more humane immigration system. Both faced criticism for the conditions in which they held migrant families. The Trump administration tried to expand the practice and detain families indefinitely to discourage migrants from crossing illegally. The Biden administration would face serious logistical obstacles in reinstating family detention, starting with finding space to hold families. Immigration and Customs Enforcement, which oversees the detention network, is already facing a budget shortfall in the hundreds of millions.
