Former Border Patrol Chief Aaron Heitke has accused the Biden-Harris administration of concealing an increase in the number of migrants with ties to terrorism crossing the U.S.-Mexico border. During a House Homeland Security Committee hearing, Heitke testified that he was instructed not to release information regarding arrests of 'significant interest aliens' (SIAs). He revealed that the number of SIAs apprehended in the San Diego sector rose from 10-15 annually before 2021 to over 100 in 2022 and even more in subsequent years. Heitke also criticized the administration for reducing migrant detention space, leading to the mass release of migrants into communities. San Diego County Supervisor Jim Desmond and other officials expressed concerns about the local and national security implications of these policies.
