As I assume the role of Acting Secretary of Homeland Security, I look forward to working to support the men and women of the Department of Homeland Security (DHS) as they carry out the critical missions that keep our country safe. I’d also like to extend my sincere thanks to Secretary Kirstjen Nielsen for her service to the country as the sixth Secretary of Homeland Security, and for her tireless work on behalf of the people and organizations of DHS. She deserves our enduring respect and appreciation for her leadership, and I’m personally grateful for it.

As you know, I submitted my resignation to the President earlier this week. Today is my final day at the Department. For nearly two years, I’ve had the honor to work alongside a talented, dedicated workforce. You serve with professionalism, respect, and determination in fulfilling DHS’ important missions. The commitment you make day in and out – securing the land air and sea domains, preventing terrorism, administrating immigration laws, ensuring disaster resilience, safeguarding our cybersecurity landscape and infrastructure, and so much more – is awe inspiring.
