Immigration and Customs Enforcement will halt nearly all deportations for 100 days, following through on a promise of President Biden, according to an internal memo directing the move.

“For 100 days, starting January 22, 2021, DHS will pause removals for certain noncitizens ordered deported to ensure we have a fair and effective immigration enforcement system focused on protecting national security, border security, and public safety,” acting Homeland Security Secretary David Pekoske said in a statement issued late Wednesday evening.
