WATCH: DHS nominee Mullin says he wants to see 'ICE become a transport more than the front line'

Sen. Elissa Slotkin, D-Mich., questioned Sen. Markwayne Mullin, R-Okla., President Donald Trump’s new pick to lead the Department of Homeland Security, about his suggestions for reforming ICE in a confirmation hearing Wednesday. Slotkin asked Mullin what he’d be “willing to do to fundamentally reform ICE.” Mullin replied that he’d like to see ICE work more with law enforcement. “I would love to see ICE become a transport more than the front line,” Mullin said in a hearing before the Senate Homeland Security and Governmental Affairs Committee. Trump tapped Mullin to take over the embattled agency from Kristi Noem, who was fired earlier this month after her leadership came under bipartisan scrutiny during tense congressional hearings. Mullin was elected to Congress in 2012 and has branded himself as a businessman and a Washington outsider. As Homeland Security secretary, Mullin, a former business owner, would take charge of one of the biggest government agencies, leading the nation’s disaster response, counterterrorism efforts, border security and the president’s mass deportation agenda. A former mixed martial arts fighter who once challenged the Teamsters president to a fight during a Senate hearing, Mullin has pledged to stay “focused on protecting the homeland" if he is confirmed. The Republican Party is considering a pivot on how it approaches immigration enforcement as more voters grow concerned over DHS agents’ aggressive tactics, which has led to the shooting deaths of at least three U.S. citizens since Trump retook office.
