CBP Released a Migrant on a Terrorist Watchlist, and ICE Faced Information Sharing Challenges Planning and Conducting the Arrest (REDACTED)

U.S. Customs and Border Protection (CBP) apprehended and subsequently released a migrant without providing information requested by the Federal Bureau of Investigation’s Terrorist Screening Center (TSC) that would have confirmed the migrant was a positive match with the Terrorist Screening Data Set (Terrorist Watchlist). This occurred because CBP’s ineffective practices and processes for resolving inconclusive matches with the Terrorist Watchlist led to multiple mistakes. For example, CBP sent a request to interview the migrant to the wrong email address, obtained information requested by the TSC but never shared it, and released the migrant before fully coordinating with the TSC.
