What happened

The White House posted a short introduction video on March 26, 2026 presenting Markwayne Mullin as the new Secretary of Homeland Security. Mullin introduced himself as his wife’s husband, from the state of Oklahoma, recently sworn in as secretary of the Department of Homeland Security, as he stated his new role.

Mullin compared protecting the homeland to the instinct to protect one’s own yard, house and family, drawing on his background in wrestling and cage fighting. He said the fact that he now gets to protect every aspect of the homeland excites him, and that he will protect viewers’ families just as he protects his own. He recounted learning of his appointment: he took off his jacket, answered a call from a 202 number he would not normally answer because presidential calls show as DJT, and about fifteen seconds into the conversation Susie Wiles walked into the office and said congratulations before the President had told him, as he told the story.

Mullin said being a father is what prepares him most for the role, because anyone who has been a dad understands how much they would do to protect their family, and he said he brings that same tenacity to protecting the homeland, which he described as a 24-hour, seven-day, 365-day job. He closed by introducing himself as the new Secretary of the Department of Homeland Security.

Why it matters

Mullin’s introduction is the new DHS secretary’s own framing of his mandate, and his account of learning of the appointment from the President’s call is the first-person record of how the department’s leadership changed hands.
