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 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.
