Fetterman backed a Trump DHS pick at a critical moment, but his reasoning is splitting Democrats

Senator John Fetterman cast the deciding vote on Thursday to advance Markwayne Mullin’s nomination for US Department of Homeland Security secretary. The move crossed party lines and sent President Donald Trump’s nominee to the full Senate for consideration.

As detailed by CNN, Fetterman explained his decision in a post on X, saying he had previously called for the removal of outgoing DHS Secretary Kristi Noem. He said he approached Mullin’s confirmation with an open mind and emphasized the need for leadership at the department, stating, “We need a leader at DHS. We must reopen DHS.” He added that his support was based on a working relationship with Mullin and concerns about national security.

The committee vote was narrow at 8-7, with Fetterman providing the deciding vote after Republican Chairman Rand Paul said he would not support the nomination. Paul’s opposition focused largely on Mullin’s temperament, which became a central issue during the confirmation process.

Concerns over Mullin’s temperament are driving the divide

During Mullin’s confirmation hearing, Paul pointed to a long-running feud between the two senators, including past comments in which Mullin called him a “snake” and referenced a 2017 attack on Paul by a neighbor. Paul said he was “shocked” by those remarks and questioned whether Mullin was suited to lead an agency responsible for enforcing federal law, with intelligence official resignation also adding to the broader national security backdrop.

Paul also cited a 2023 hearing in which Mullin appeared ready to confront a witness physically. He pressed Mullin for an apology during the hearing, but Mullin declined and instead urged both sides to move forward, saying he would work to earn respect and prove himself in the role.

Fetterman later encouraged both senators to move past their personal conflict, acknowledging the seriousness of political violence while urging a focus on the nomination itself. He also noted that Sean O’Brien, president of the International Brotherhood of Teamsters and a witness at the 2023 hearing, had expressed support for Mullin.

Opposition to Mullin is not limited to Paul. Senator Gary Peters, the top Democrat on the committee, said he would vote against the nomination and questioned whether Mullin has the necessary experience and temperament to oversee a department of more than 260,000 employees.

If confirmed, Mullin would lead a department that includes agencies such as Immigration and Customs Enforcement, the Transportation Security Administration, and the Coast Guard, as visa bond expansion adds to the wider immigration debate. Senate Majority Leader John Thune has said a full Senate vote on the nomination could take place early next week.
