Overview
- DHS says more than 100 Coast Guard vessels and hundreds of personnel are deploying, including response boats, shallow‑water craft, command assets and tactical teams.
- The mission is described by DHS as controlling, securing and defending roughly 265 miles (426–427 km) of the Rio Grande Valley.
- Tactical operations fall under Coast Guard Rio Grande forces with coordination across federal and state agencies, and interim Admiral Kevin E. Lunday touts the service’s riverine interdiction expertise.
- Secretary Kristi Noem frames the push as consolidating gains under President Trump, with DHS citing a tripling of southern‑border assets and a 75% rise in apprehension rates since January, figures provided by the agency.
- The announcement coincided with intensified immigration raids that drew protests in New York and a Los Angeles incident that left an agent and a civilian injured, according to DHS accounts reported by local media.
