WASHINGTON — A Monday night Senate vote to confirm Sen. Markwayne Mullin of Oklahoma as secretary of Homeland Security highlighted a familiar divide in Washington, with strong party unity and only limited bipartisan support.
The final vote, 54-45, largely followed party lines. But two Democrats — Sens. John Fetterman of Pennsylvania and Martin Heinrich of New Mexico — joined Republicans to push Mullin across the finish line.
Their support didn’t change the outcome on its own, but it stood out in a confirmation process closely watched for signs of bipartisan movement in President Donald Trump’s second term.
A Decisive Committee Moment
Fetterman’s role began earlier, and it carried more weight.
In the committee stage, he was the only Democrat to vote in favor of advancing Mullin’s nomination. That vote proved decisive in an 8-7 outcome after Sen. Rand Paul (R-Ky.) broke with his party and voted no, citing Mullin’s failure to condemn an assault against him.
Without Fetterman’s vote, the nomination would have stalled.
The move drew immediate criticism from fellow Democrats, some of whom argued it undercut party unity on a key national security post. It also put a spotlight on internal disagreements over how to approach immigration enforcement and DHS leadership.
A Broader Split on Security Issues
Fetterman’s vote fits a pattern. He has shown a willingness to cross party lines, particularly on national security and border-related issues. Heinrich’s support was less expected but pointed in the same direction.
For Republicans, the votes offered a measure of bipartisan cover for a nominee tied closely to Trump’s agenda. For Democrats, they highlighted ongoing tension between moderates and more progressive members over border policy and federal enforcement priorities.
Why It Matters
Cabinet confirmations often fall along predictable lines. Even so, defections carry political weight.
Here, the backing from Fetterman and Heinrich underscored a deeper divide within the Democratic Party — one that continues to surface on issues tied to immigration, law enforcement, and federal authority at the border.
The Bottom Line
In the end, only two Democrats supported Mullin’s confirmation. That made Fetterman and Heinrich the lone members of their party to side with Republicans on one of the most closely watched Cabinet votes so far in Trump’s second term.
