Sen. Markwayne Mullin was confirmed as the ninth Homeland Security secretary in a vote that closes his 13-year stretch in Congress and opens a new, high-stakes chapter for border and immigration policy. The move happened amid a continuing DHS funding fight, party-line divisions, and tense talks in the Senate over how to reopen the department. This article covers Mullin’s rise, the confirmation math, the political fallout, and the friction that still threatens a resolution to the shutdown.
The Senate’s confirmation of Mullin caps a rapid transition after the reassignment of the previous secretary and a string of explosive hearings on Capitol Hill. Surrounded by family, Mullin stood tall and cast his final vote, a symbolic bookend to his time in the Senate. Supporters see his confirmation as a win for straightforward leadership at DHS.
Mullin’s run in Congress began in the House and moved to the Senate in 2021, building a reputation as a dealmaker between chambers during last year’s push to pass the “big, beautiful bill.” That background sold many Republicans on his ability to navigate complex, cross-branch fights. It’s the kind of practical experience party leaders say the homeland security portfolio needs right now.
The confirmation came on a largely party-line vote, with two Democrats breaking ranks to join Republicans in support. Sen. Martin Heinrich explained his decision by saying Mullin “is not someone who can simply be bullied into changing his views.” “And I look forward to having a secretary who doesn’t take their orders from Stephen Miller,” Heinrich added, signaling that some Democrats respect Mullin’s independence.
Not every Republican was on board. Sen. Rand Paul was the lone GOP no vote, pointing to a chilly relationship and Mullin’s past remark that his 2017 assault was “justified.” Those concerns were loud in some corners, but they did not stop the confirmation from moving forward.
Mullin takes over DHS amid a fraught environment: a shutdown that has lasted weeks, intense scrutiny over enforcement actions, and the fallout from several high-profile incidents, including the deaths of Renee Nicole Good and Alex Pretti. Republicans argue leadership changes are needed to restore order and accountability while maintaining strong enforcement at the border.
Democrats have been steadfast in their demands for broad reforms to ICE and have repeatedly blocked funding for the agency, voting down measures to sustain it five times. GOP efforts to decouple funding or extend short-term fixes have run into unified Democratic opposition, and that blockade has prolonged the impasse.
Over the weekend, Senate leaders opened talks for the first time since the shutdown began, with both sides calling the initial meetings “productive.” Still, the negotiations quickly became complicated when strategy and demands collided on the details of how to fund DHS and which priorities to include in any package.
President Trump injected a new condition into the talks via Truth Social, writing, “I don’t think we should make any deal with the Crazy, Country Destroying, Radical Left Democrats unless, and until, they vote with Republicans to pass ‘THE SAVE AMERICA ACT.’” He followed that with, “In other words, lump everything together as one, and VOTE!!! Kill the Filibuster, and stay in D.C. for Easter, if necessary,” a blunt signal that he wants leverage and big concessions.
Senate GOP leaders floated an alternative: carve out ICE and Customs and Border Protection funding from a broader DHS bill and push those items through reconciliation instead. That approach would bypass some of the obstruction, but canceling an upcoming recess to press the issue may be a tough sell given attendance problems during recent votes. When asked if he would cancel the two-week break, Thune said, “We’ll see.”
A group of Senate Republicans met with the president before Mullin’s confirmation vote, and Sen. Katie Britt reported the discussion went “really well.” On whether Republicans have a plan to end the shutdown, she told reporters, “We do,” reflecting the party’s confidence in a strategy that combines pressure, targeted funding moves, and high-level negotiation.
Despite the change at DHS, Senate Democrats remain united against the Safeguarding American Voter Eligibility (SAVE) Act and continue to press for sweeping immigration changes tied to DHS funding. “We’re ready to meet with the White House today to keep talking,” Schumer said. “In fact, we were going to meet this morning with Tom Homan. But apparently the White House pulled that meeting because of Donald Trump’s temper tantrum. They’re all scrambling around there in the White House. They don’t know what to do.”
