Markwayne Mullin moved one step closer to becoming the next Secretary of the Department of Homeland Security after clearing a crucial procedural vote in the Senate on Sunday (March 22). The 54–37 vote, largely along party lines, sets up a final confirmation vote expected Monday evening.

If confirmed, Mullin would replace Kristi Noem, who was dismissed by Donald Trump following controversy surrounding immigration enforcement operations.

Final vote looms after contentious hearing Despite clearing the initial hurdle, Mullin still faces a decisive confirmation vote. His path has been marked by a heated confirmation hearing, where lawmakers from both parties scrutinized his past statements and conduct.

Among his critics was Rand Paul, with whom Mullin has a history of personal clashes. Mullin previously referred to Paul as a “snake” and defended a past physical altercation, positions he did not fully walk back during testimony.

“I’m not perfect. I don’t claim to be perfect,” Mullin said. “I make mistakes just like anybody else. But mistakes, if you own them, you can learn from them and you can move ahead.”

Bipartisan movement amid party divides While the vote was mostly split along party lines, a few Democrats broke ranks. Martin Heinrich and John Fetterman supported advancing Mullin’s nomination, signaling limited bipartisan backing.

Fetterman had also played a pivotal role earlier in the week by helping move Mullin’s nomination out of committee.
