I’ll explain why Senator Peter Welch’s praise for Markwayne Mullin matters, outline the controversy surrounding Kristi Noem’s exit, quote key reactions from both sides, and note what Mullin’s move means for the Senate and Homeland Security.
Democratic Sen. Peter Welch surprised some viewers when he spoke positively about Republican Sen. Markwayne Mullin after President Trump tapped Mullin to take over the Department of Homeland Security from Kristi Noem on March 31. Welch told CNN’s “The Arena” that Mullin is “competent,” “honest” and “respected,” calling attention to qualities many Republicans have highlighted for months. The endorsement leans into a rare bipartisan note in a fiercely partisan moment.
Noem’s tenure had become a lightning rod after two fatal DHS-related incidents in Minnesota and intense questioning during Congressional oversight hearings. She also faced media scrutiny over alleged personal matters tied to a top aide, which amplified calls for accountability from across the aisle. Those events set the stage for a change at DHS that Trump announced publicly on his platform.
Welch said bluntly, “He’ll be confirmed. The question is whether there’ll be bipartisan support for him. Markwayne Mullin is competent, and he’s honest. So those are two good things that Kristi Noem did not have,” and he argued the move gives lawmakers a chance to address systemic failures. He stressed that what happened in Minneapolis must never happen again and framed Mullin’s nomination as an opportunity to refocus the department’s mission. That kind of straight talk from a Democrat helps the nomination’s optics in Washington.
Welch doubled down later with another clear line: “He’s respected, he’s honest and he’s competent.” He made a point that the real debate will be over policy choices Mullin will bring, not his character. That distinction matters because it reframes opposition as policy-driven rather than personal, which can open the door to cross-aisle dialogue.
President Trump praised Mullin’s blend of House and Senate experience and called him a strong advocate for Tribal communities as the first American Indian tapped for DHS. Trump wrote, “Markwayne will work tirelessly to keep our border secure, stop migrant crime, murderers, and other criminals from illegally entering our country, end the scourge of illegal drugs and, make America safe again,” Trump wrote. “Markwayne will make a spectacular Secretary of Homeland Security.”
There are signs of cautious support and skepticism from across the Capitol. Democratic Sen. John Fetterman signaled some uncertainty about how many colleagues would back Mullin, and his public reaction included commentary on X. That hesitation mirrors the fine line Democrats must walk between criticizing policy and acknowledging a nominee’s personal reputation.
Mullin has also spoken directly about the nomination and his intentions for the role. “I am grateful to President Trump for nominating me to lead the U.S. Department of Homeland Security,” Mullin wrote. “I look forward to earning the support of my colleagues in the Senate and carrying out President Trump’s mission alongside the department’s many capable agencies and the thousands of patriots who keep us safe every day.” That pledge highlights the narrow, results-focused message Republicans want heard.
Practically, Mullin’s move out of the Senate creates a vacancy in Oklahoma, leaving Governor Kevin Stitt to name a successor. That choice will have immediate political consequences for control and committee assignments in the chamber. For Republicans, it’s a high-stakes sequence: confirm Mullin, secure the DHS nomination, and then shore up the Senate seat through the governor’s appointment process.
Republican supporters point to Mullin’s reputation for getting along with colleagues and his track record on border and public safety issues as reasons to expect smooth Senate action. Critics will, of course, press on policy specifics and demand clarity on how he’ll handle DHS priorities beyond rhetoric. The coming confirmation process will be where those promises meet scrutiny.
