Scott Applewhite)2026-03-17T04:23:40Z WASHINGTON (AP) Should Sen. Markwayne Mullin be approved as the next secretary of Homeland Security, he will walk into the departments sprawling Washington, D.C., campus with his work cut out for him.Immigration enforcement is at a crossroads. Disaster-hit states and their lawmakers are angry at delayed federal assistance. Frustrated travelers face long airport security lines due to a monthlong funding battle in Congress.Mullin would take over from embattled outgoing secretary Kristi Noem, who entered office with President Donald Trumps backing but whose social media-driven management style of the governments third-largest department contributed to her downfall.Weve got serious management problems at DHS, and we need somebody steering the ship, said Sen. John Kennedy, R-La., adding that he told the Oklahoma senator a full audit of the department is needed.Mullin, a former mixed martial arts fighter, has earned a reputation as a combative presence in the Senate. After 13 years in Congress, he has the confidence of fellow lawmakers and is expected to follow the White Houses policy priorities. His confirmation hearing is set for Wednesday. Mullin would oversee immigration enforcementA top challenge for Mullin would be taking over the administrations centerpiece policy of mass deportations, which has triggered a surge of immigrant arrests, sparked fear in communities and raised concerns about detention and enforcement tactics.A year of high-profile operations resulted in high arrest numbers but also criticism that officers were too aggressive. The shooting deaths of two protesters in Minneapolis by federal officers sparked calls for reform at immigration enforcement agencies.Approval of Trumps immigration approach is down from when he started his second term, with most Americans saying Trump has gone too far. The souring public mood could force Mullin to recalibrate how the agencies he would oversee implement the deportation push. Since being nominated, Mullin has not publicly revealed his vision for running the department and has declined to answer questions. He is likely to be a faithful ally to Trump in his new role. In the Senate, he has been less focused on legislation and more engaged as a de facto spokesman for the White House talking to the president often and amplifying his messages in the hallways of the Capitol and behind closed doors. He has been a strong supporter of Immigration and Customs Enforcement officers and the congressional funding approved last summer that super-charged immigration enforcement.Following the shooting deaths of the U.S. citizens in Minneapolis, he backed law enforcement and blamed local leaders for rhetoric that he said had emboldened protesters.John Sandweg, a former acting director at ICE during the Obama administration, said Mullin will need to balance pressures from different players inside the administration over how to conduct future enforcement operations whether to ramp up deportations through arrest sweeps or keep enforcement more targeted on people whove committed crimes. Hes going to have to reconcile ... are we about numbers or about quality? said Sandweg. And I think hell face a lot of pressure to also deliver on numbers. First challenge for Mullin will be the DHS funding lapseMullin is also walking into a battle with congressional Democrats demanding reforms at ICE, which has led to a monthlong lapse in funding for DHS.Senate Democrats want changes to immigration enforcement before they approve more money. That includes a ban on masks worn by deportation officers, an end to roving patrols of officers looking for immigrants and a requirement that officers use warrants signed by a judge to enter a persons house. Republicans have held the line against those demands.As the standoff has dragged on, thousands of Homeland Security staffers are being forced to work without pay, including airport security screeners. Some airports have started to see long security lines, raising concerns that screeners are calling out sick, taking on side jobs to make ends meet, struggling with fuel costs or leaving their jobs altogether. In his new role, Mullin is expected to improve relationships with Congress, where Republicans treated Noem with skepticism. He is close to both House Speaker Mike Johnson, R-La., and Senate Majority Leader John Thune, R-S.D. Republicans are hoping that switching out Noem for Mullin will serve as enough of a change to appease Democratic demands to fund the department.This is what the Democrats have been clamoring for. They wanted a new change and shake-up in the leadership, and its now happening, said Thune.But Democrats have insisted on widespread changes.I like Markwayne personally, but I dont think its a question of who is at the helm, its a question of law, said Sen. Brian Schatz, D-Hawaii. States clamoring for change at disaster response agencyMullin will also inherit a Federal Emergency Management Agency mired in upheaval and uncertainty over the administrations attempts to shift disaster responsibility to states and Trumps threats to abolish the agency.DHS under Noem drove a torrent of policies in the name of that objective, stalling funding, driving out staff and attracting lawsuits over just how much authority a homeland security secretary could exert over FEMA, which still lacks a permanent administrator.Noem enacted a policy that she personally approve expenditures over $100,000, which critics said delayed billions in disaster recovery dollars. State emergency managers hope to see a quick repeal, along with the release of grant funding for preparedness and resilience, said Karen Langdon, a National Emergency Management Association spokesperson. There are still over $2.2 billion in recovery and mitigation projects awaiting DHS approval as of Friday, according to official figures seen by The Associated Press. The Trump-appointed FEMA Review Council, chaired by Noem, is months behind in releasing a highly anticipated recommendation report after the outgoing secretary clashed with other council members on how far to take the reforms.Mullins views on FEMA arent entirely clear, but he has expressed skepticism of a federal disaster response in the past. Its not FEMA thats going to respond, he told Fox Business shortly after Hurricane Helene in 2024. Its the local people that are going to respond, and were going to be fighting with FEMA to get reimbursed if they ever do reimburse.Lawmakers and states generally support reforms that would streamline disaster aid and ease bureaucratic burden, but state and local governments need dependable leadership and time to prepare for changes, said Sarah Labowitz, senior fellow at the Carnegie Endowment for International Peace.What we want to see going forward is predictability, Labowitz said. Theres a lot of work to be done to re-earn trust.___Associated Press reporters Mary Clare Jalonick, Kevin Freking and Stephen Groves contributed to this report.
