Homeland Security Secretary Markwayne Mullin defended the current U.S. southern border strategy during a visit to Brownsville, Texas.

The secretary's comments come amid ongoing debates regarding the effectiveness of border security and criticism over his professional experience in the role.

Speaking from the border, Mullin said the administration has achieved 15 straight months of zero migrant releases [1]. This figure serves as a central pillar of his defense against critics who have questioned his ability to manage the Department of Homeland Security.

Mullin also praised the partnership between the federal government and the state of Texas regarding the construction and maintenance of the border wall. He said the collaboration is essential to the current security posture, a strategy he said is fully supported by the executive branch.

When asked about his relationship with the presidency, Mullin said, "President Trump and I are always on the same page."

The secretary's visit to Brownsville was designed to counter claims that he is too inexperienced to lead the department. These criticisms had previously surfaced in political circles, including reports from March 2026 that highlighted clashes between administration officials and critics over his appointment.

Mullin said that the results on the ground prove the efficacy of the current approach. He said that the lack of releases over the last 15 months [1] demonstrates a commitment to strict enforcement that differs from previous administrations.

"We have had 15 straight months of zero releases."

The assertion of zero migrant releases for over a year represents a significant shift in border processing policy. By emphasizing a total lack of releases and a tight partnership with Texas, the DHS is signaling a move toward a zero-tolerance enforcement model intended to deter illegal crossings through immediate detention or removal.
