The Senate confirmed Markwayne Mullin as homeland security secretary on Monday.

… Mr. Mullin, a Cherokee Nation member who was sworn in as Oklahoma’s junior senator in 2023, will take charge of the Homeland Security Department at a pivotal time. Recent polling has shown that Republicans’ advantage on immigration is shrinking and that most Americans believe that immigration agents have gone too far, especially after the fatal shootings of two U.S. citizens in Minneapolis in January. Mr. Mullin will have to balance the task of mending the agency’s image while also delivering on President Trump’s signature campaign promise of mass deportations.
He will also take the reins at a time when thousands of department employees are working without pay amid a partial government shutdown that has led to scenes of chaos at airports across the country. On Monday, Mr. Trump deployed more than 100 immigration agents to airports in an effort to ease long security lines as the ranks of Transportation Security Administration officers have thinned…
At his confirmation hearing, Mr. Mullin made clear that he was committed to fulfilling the administration’s crackdown on illegal immigration. But he also tried to strike a more cooperative tone, saying that immigration officers would generally no longer enter homes without a judicial warrant under his leadership. And he said the department would foster closer relationships with jails, suggesting a move away from sweeping operations in Democratic-led cities and states…
A close ally of Mr. Trump and a staunch defender of his policies, Mr. Mullin was sworn in as a senator after a decade of serving in the House. He had a brief stint as a mixed martial arts fighter and took over his family’s business, Mullin Plumbing, at the age of 20.
I would generally say that leaving the senate to take DHS director indicates that he doesn't want to be in the minority senate, tbh.

There is also the possibility he saw Noem's grift racket and thought "maybe if I just do it a little bit less.."

About that… Per the NYTimes, “How Trump’s Homeland Security Pick, a Prolific Investor, Got a Lot Wealthier in Congress” [gift link]
Our outnumbered Democrats went down fighting, and took markers:
I will hold Mullin to every one of his promises.
