The Senate Homeland Security and Governmental Affairs Committee advanced Mullinâs nomination on March 19, 2026, by an 8-7 vote.
Republicans hold an 8-7 edge on the committee; Chair Sen. Rand Paul (R-Ky.) voted âno,â citing âanger issuesâ and a prior conflict he described as involving a âviolent attackâ justification.

No Democrats besides Sen. John Fetterman (D-Pa.) voted âyesâ; Fettermanâs vote prevented the nomination from stalling in committee. ([nbcnews.com](https://www.nbcnews.com/politics/congress/trumps-dhs-pick-mullin-advances-one-vote-sen-fetterman-votes-yes-rcna264207))
The nomination now goes to the full Senate, where Mullin will need a simple majority; the article says a floor vote could occur next week and that Trump wants him to start by March 31.

NBC reports DHS is dealing with backlash over immigration enforcement tactics, the war in Iran, and airport delays after DHS funding lapsed on Feb. 13; the article does not quantify the lapseâs effects or clarify what âreopen DHSâ means operationally.

Top committee Democrat Sen. Gary Peters (D-Mich.) argued Mullin was not forthright/transparent and lacks the experience/temperament to lead DHS. ([nbcnews.com](https://www.nbcnews.com/politics/congress/trumps-dhs-pick-mullin-advances-one-vote-sen-fetterman-votes-yes-rcna264207))
Separate contemporaneous coverage adds that the hearing included questions about Mullinâs past comments, immigration policy, and a foreign trip Mullin described as âclassified,â which helps explain the âtransparencyâ line of attack but is only lightly conveyed in the NBC excerpt.
