唐纳德·特朗普总统在经历数周内部动荡后，缩短了克里斯蒂·诺姆（Kristi Noem）在国土安全部的任期。如今，这位昔日保守派明星即将赴任新的特使职位，却面临一个紧迫问题：她能否实现政治复出？
诺姆因内部冲突不断和两次有争议的国会听证会而动荡不安，期间甚至有部分共和党人就其领导失误向她施压，最终被解职为国家移民负责人。特朗普在Truth Social平台宣布，俄克拉荷马州共和党参议员马克韦恩·穆林（Markwayne Mullin）将从3月31日起接替她的职位，而诺姆将转任总统所谓本周末将详细说明的新设立的特使职务。
一位政府消息人士告诉福克斯新闻，是时候让诺姆离开，原因是内部争斗、员工管理不善以及争议事件——包括一场2亿美元的广告宣传活动和明尼苏达州的风波——“掩盖”了特朗普的移民议程。
“克里斯蒂的风波令人遗憾地掩盖并分散了政府极为受欢迎的移民议程的注意力，而该议程将继续全力推进，”消息人士表示。
特朗普称，诺姆将被任命为“美洲盾牌特使”，这是一个新设立的职位，他将其描述为更广泛的西半球安全倡议的一部分。白宫尚未详细说明该职位的职责范围。
此次调任正值南达科他州关于诺姆是否会在2026年挑战参议员迈克·鲁恩兹（Mike Rounds）的猜测不断升温之际——这一行动将考验她在特朗普和共和党选民中的地位是否真的有所削弱。
寻求第三个任期的鲁恩兹去年获得了特朗普的“完全支持”，并得到参议院共和党领导层的支持——这对任何挑战者来说都是一道难以逾越的障碍。“他永远不会让你失望，”特朗普在支持声明中写道，称鲁恩兹是“美国优先爱国者”。
福克斯新闻数字版已联系鲁恩兹办公室请求置评。
诺姆在进入任何竞选活动时都具有全州范围内的知名度和深厚的政治网络，她在赢得两任州长之前曾在国会任职八年。
但一些共和党人士质疑，在关键政治时刻，她突然退出国土安全部是否削弱了她在特朗普核心圈子中的地位。一位参与参议院竞选的共和党策略师承认，诺姆曾是MAGA运动的摇滚明星，但形容此时潜在的参议院竞选是一场“自杀任务”。
时间紧迫。南达科他州的候选人报名截止日期为中部时间3月31日下午5点，候选人必须在三周多一点的时间内收集约2200个请愿签名，才有资格参加6月2日的初选。
诺姆抨击民主党阻挠国土安全部资金法案 称其影响TSA、FEMA、海岸警卫队：“我希望他们醒悟过来”
这场猜测已引起全国关注。《大西洋月刊》报道称，南达科他州的民调机构正在调查鲁恩兹与诺姆的潜在对决，一位共和党消息人士告诉该杂志，参议员如果受到挑战将“轻松获胜”。
拉皮德城的ABC affiliate在2月份报道了诺姆野心的传闻，称她家乡州的共和党人正关注她是否会挑战鲁恩兹。
尽管如此，诺姆在家乡仍有不少强大盟友。皮埃尔市诺姆的继任者州长拉里·罗登（Larry Rhoden）周四评论道：“克里斯蒂是我的好朋友，也是我认识的最坚强的人。”
“当她创纪录地关闭边境时，其他人都感到震惊，但我并不意外。我知道她的能力。”
“她在新职位上也会同样出色。感谢她为保持南达科他州乃至整个美国的强大、安全和自由所做的一切，”罗登说。
罗登在担任州长期间，与诺姆领导的国土安全部合作，使南达科他州成为首批签署287(g)协议的州之一，该协议允许州级与移民和海关执法局（ICE）合作。根据这项安排，南达科他州公路巡逻队被授权协助移民执法，国民警卫队人员也支持行政职能——这一业绩可能会在关于她下一步行动的猜测加剧时，增强她在保守派初选中的地位。

Kristi Noem’s political future uncertain amid Senate primary rumors | Fox News
By Charles Creitz, Paul Steinhauser | Fox News
Published March 7, 2026 6:00am EST
President Donald Trump cut short Kristi Noem’s tenure at the Department of Homeland Security after weeks of internal turmoil. Now headed to a new envoy post, the onetime conservative star faces a pressing question: Can she stage a political comeback?
Noem was fired as the nation’s immigration chief after a turbulent stretch marked by internal clashes and two contentious congressional hearings where even some Republicans pressed her over leadership missteps. Trump announced on Truth Social that Sen. Markwayne Mullin, R-Okla., will replace her effective March 31, while Noem shifts to a newly created envoy role the president says he’ll detail this weekend.
An administration source told Fox News “it was time” to move on from Noem, citing internal feuding, staff mismanagement and controversies — including a $200 million ad campaign and fallout in Minnesota — that “overshadowed” Trump’s immigration agenda.
“Kristi’s drama sadly overshadowed and distracted from the Administration’s extremely popular immigration agenda, which will continue full force,” the source said.
Trump said Noem will be named “Special Envoy for The Shield of the Americas,” a newly created role he described as part of a broader Western Hemisphere security initiative. The White House has not yet detailed the scope of the position.
The reassignment comes as speculation grows in South Dakota over whether Noem could mount a primary challenge against Sen. Mike Rounds in 2026 — a move that would test whether her standing with Trump and GOP voters has truly eroded.
Rounds, who is seeking a third term, secured Trump’s “complete and total endorsement” last year and is backed by Senate Republican leadership — a formidable barrier to any challenger. “He will never let you down,” Trump wrote in his endorsement, calling Rounds an “America First Patriot.”
Fox News Digital reached out to Rounds’ office for comment.
Noem would enter any race with statewide name recognition and a deep political network, having served eight years in Congress before winning two terms as governor.
But some Republican operatives question whether her abrupt exit from DHS weakened her standing within Trump’s inner circle at a critical political moment. One GOP strategist involved in Senate races, who acknowledged that Noem was once a MAGA rock star, described a potential Senate bid at this time as a “suicide mission.”
The clock is already ticking. South Dakota’s filing deadline is March 31 at 5 p.m. CT, and candidates must gather roughly 2,200 petition signatures in just over three weeks to qualify for a June 2 primary.

The speculation has drawn national attention. The Atlantic reported that pollsters in South Dakota were surveying a potential Rounds-Noem matchup, with one Republican source telling the magazine that the senator would “handily win” if challenged.
Rapid City’s ABC affiliate reported on the rumors of Noem’s ambitions in February, saying Republicans in her home state are watching to see if she would challenge Rounds.
Still, Noem has a fair share of powerful allies back home. Gov. Larry Rhoden, Noem’s successor in Pierre, commented Thursday that “Kristi is a dear friend and the toughest person I know.”
“When she shut down the border in record time, others were shocked, but I wasn’t. I knew what she was capable of.”
“She’ll deliver in her next role just as capably. I thank her for everything she’s done to keep South Dakota — and all America — strong, safe, and free,” Rhoden said.

As governor, Rhoden worked with Noem’s DHS to make South Dakota one of the first states to enter a 287(g) agreement allowing state-level cooperation with ICE. Under the arrangement, the South Dakota Highway Patrol has been authorized to assist with immigration enforcement, and National Guard personnel have supported administrative functions — a record that could bolster her standing with conservative primary voters as speculation about her next move intensifies.
