Donald Trump announced the firing of Kristi Noem as US Homeland Security Secretary, following weeks of bipartisan criticism over her leadership after two US citizens were killed by immigration agents and reports of a personal relationship with a senior deputy.
Noem’s departure marks the first major personnel shake-up of Trump’s second term. She will be replaced by Republican Senator Markwayne Mullin of Oklahoma, who is set to take office on 31 March. Noem will assume a new role as special envoy for the “Shield of the Americas” security initiative.
Mixed reactions in Washington
While Noem thanked Trump for the new appointment and defended her record, Democrats hailed her removal. House Minority Leader Hakeem Jeffries described her tenure as a “disaster” but noted that personnel change alone is insufficient without broader policy reform. Senate Majority Leader Chuck Schumer echoed concerns over the deep structural issues within DHS.
Some Republicans also acknowledged the need for change. Senator Lindsey Graham stated that while Noem had served the country well, the timing was right for new leadership.
Controversies during tenure
Noem became a prominent figure in Trump’s immigration crackdown, which targeted both documented and undocumented immigrants, as well as some US citizens. She faced intense criticism following the deaths of Renee Good and Alex Pretti in Minneapolis, whom she accused of “domestic terrorism”, claims that Democrats and some Republicans rejected.
Reports also highlighted turmoil within DHS, including Noem’s personal relationship with senior adviser Corey Lewandowski, the administration of polygraph tests to staff, and the use of a luxury 737 Max jet for department travel. Questions were raised about mismanagement of funds and her public promotion in DHS advertising campaigns.
Political and ethical concerns
Noem also faced scrutiny over past decisions, including killing a dog and a goat, which she documented in a memoir, and was a factor in her being passed over as Trump’s running mate in 2024. Several Republican senators, including John Kennedy and Thom Tillis, expressed concerns about her management, raising issues of obstruction and questionable expenditures.
