How will Markwayne Mullin's leadership affect the United States Department of Homeland Security?
DHS shifts focus to aggressive enforcement while election security capacity shrinks Under Secretary Markwayne Mullin, the Department of Homeland Security (DHS) has significantly intensified its immigration enforcement operations, reporting record arrests and deportations of criminal aliens. Simultaneously, the agency's election security capacity has been curtailed, as the administration dismantled much of the Cybersecurity and Infrastructure Security Agency's (CISA) role, leading to reduced federal support for state and local election officials.

How it reaches United States Department of Homeland Security
-
The U.S. Cybersecurity and Infrastructure Security Agency released an election infrastructure security plan 40 days before the November midterms. The plan was announced by Homeland Security Secretary Markwayne Mullin, who had originally promised its release by mid-August. Election officials criticized the plan as inadequate and belated, noting the Trump administration had gutted the agency’s election security work the previous year. This criticism was made while the administration also faced scrutiny over the increased deportations of convicted criminals under Mullin's leadership.

Why it matters
The DHS is currently operating under a mandate of aggressive border enforcement and mass deportation, a policy championed by President Donald Trump and Secretary Mullin. This focus on removing public safety threats and securing the border has led to record arrests and deportations of criminal aliens, fulfilling the administration's stated commitment to national safety.
However, this aggressive enforcement comes at the cost of other mandated functions. The gutting of CISA's election security role has created gaps in federal support, forcing state and local officials to rely on private vendors for security testing, highlighting a significant shift in how the department prioritizes its various responsibilities.
