The U.S. Coast Guard is preparing to hold a press conference this Thursday to outline its patrol operations along the southern border, including efforts at the Rio Grande as part of the initiative known as Operation River Wall.

This press briefing is set for 2 p.m. in Mission, Texas. Earlier this month, the Department of Homeland Security unveiled Operation River Wall as a continuation of the Trump administration’s stringent measures against illegal immigration. This initiative represents the largest surge in border enforcement by the Coast Guard in many years.
