Gregory Bovino, a senior U.S. Border Patrol official known for leading aggressive immigration raids in major cities, is retiring at the end of this month amid controversy. His tenure included criticized operations in Los Angeles and other cities, culminating in backlash after fatal shootings during an enforcement action in Minneapolis and legal challenges over his tactics. Bovino’s retirement coincides with leadership changes at the Department of Homeland Security and marks the conclusion of a contentious period in Trump-era immigration enforcement.
