Markwayne Mullin Sworn In as Ninth U.S. Secretary of Homeland Security, Issues Message to DHS Workforce

March 24, 2026 - WASHINGTON, D.C. - Newly sworn‑in Secretary of Homeland Security Markwayne Mullin delivered his first official message to Department of Homeland Security employees today, outlining his priorities and expressing appreciation for the workforce during the ongoing government shutdown.

Secretary Mullin, who took the oath of office earlier in the day, emphasized his commitment to carrying out President Donald Trump's homeland security agenda. In his message, he highlighted what he described as major accomplishments under the current administration, including strengthened border security measures.

"I am honored that President Trump entrusted me to lead DHS and fulfill his mission of securing the homeland and keeping the American people safe," Mullin wrote, calling the department's recent efforts "historic successes."

Mullin pledged to work closely with DHS personnel across all components, citing a broad mission set that includes border security, immigration enforcement, cybersecurity, disaster response, and counterterrorism. He underscored the importance of the department's work "by air, land, sea, or in cyberspace," and praised employees for continuing to serve during the shutdown despite not receiving pay.

"The fact that you continue to show up and do your job without pay says a lot about your character and commitment to this mission," he said, adding that securing funding to reopen the department is his "number one priority."

Mullin also expressed gratitude for the workforce's resilience and reaffirmed his intention to advocate for the resources DHS needs to operate effectively. He closed his message with a call to unity and service, invoking a phrase he said guides his leadership: "love the people, love the call."

As the department enters a new chapter under Mullin's leadership, attention now turns to how DHS will navigate ongoing operational demands, budget negotiations, and the broader national security landscape.
