Oklahoma Senator Markwayne Mullin promised a better approach on immigration enforcement and, despite recent criticism of the Homeland Security department, pledged that as its leader he would be protecting everybody.

The senator's remarks came as he was questioned by colleagues considering his nomination to lead the Department of Homeland Security (DHS) following Kristi Noem's departure earlier this month. Reopening the department amid the partial government shutdown, potential growth of Immigration and Customs Enforcement (ICE) centres across the US, and ICE's use of judicial warrants all came up during the three-hour hearing.

Mullin is vying for the job as the DHS enters its fifth week without funding, and concerns surrounding a lack of pay for workers loomed during questioning. The committee expects a vote on Thursday on Mullin's nomination, which would move to a full Senate vote next.

Mullin regrets Alex Pretti remarks

Many questions from senators focused on ICE and opposition the agency has faced due to increased federal immigration efforts in cities across the US. Michigan Senator Gary Peters pressed Mullin about his comments regarding Alex Pretti, a man shot and killed by federal agents in January. Previously, Mullin stated that Pretti was deranged; however, he later expressed regret over these comments but deferred a direct apology until the investigation concludes.

Mullin stated, I can have different opinions with everybody in this room, but as Secretary of Homeland I’ll be protecting everybody. My goal in six months is that we’re not in the lead story every single day.

DHS shutdown on everyone's minds

The DHS has been without funding since February, causing significant anxiety among employees. The shutdown was emphasized during Mullin’s hearing, as many expressed concern about its impact on the safety of American citizens.

Senator Rand Paul, Republican committee chair, voiced skepticism over Mullin's capabilities, questioning his past remarks on political violence and expressing concern about his character. This led to a heated exchange between Mullin and Paul.

Despite the confrontations, it appears there are enough bipartisan votes to advance Mullin's nomination, pending the outcome of Thursday’s committee vote.

A feud comes to an end

In a surprising development, Mullin reconciled with Sean O'Brien, president of the International Brotherhood of Teamsters, who had previously been at odds with him. Their unexpected friendship was a highlight during the emotionally charged hearing.
