明尼阿波利斯发生一起引发全国震惊的事件：ICU 护士 Alex Pretti 在周六遭边境巡逻人员开枪致死。这起枪击不仅激起广泛反感，也暂时压过了重大新闻常见的党派口水，并开始重组两党内部的结盟与分歧，可能在未来数周到数月改变全国政治的走向。
最明显的转折讯号，是总统特朗普在周一改派「边境事务主管」Tom Homan 接手明尼苏达局势，形同让国土安全部长 Kristi Noem 与边境巡逻指挥官 Gregory Bovino 退居次位。此举被视为可能要终止在双子城地区的流动式、带有暴力色彩的扫荡行动；此前行动导致一名 5 岁孩童被蒙面联邦人员拘留，并造成两名美国公民死亡：1 月 7 日的 Renee Good 与此次的 Pretti。白宫称 Homan 将直接向特朗普报告，他以偏好「更精准、锁定有犯罪纪录移民」的执法方式著称。
即使在本周末暴力事件前，明尼苏达的混乱景象已让共和党感到棘手：特朗普部署 ICE 引发愤怒反弹，并开始侵蚀他原本最具优势的移民议题。1 月 23 日《纽约时报》/Siena 的民调显示，63% 的美国人不认同 ICE 的执法方式，甚至每 5 位共和党人就有 1 位认为该机构「做得太过火」。共和党内也出现焦虑与裂痕，例如明尼苏达共和党人 Chris Madel 退出州长选战并退党；同时，Pretti 之死也让民主党内「对抗派」压过温和派，多名温和派参议员表态若无执法改革就不再支持国土安全部预算，主张要求司法令状、现场清楚表明身分与加强训练。僵局让政府再度面临停摆风险：若参院未在周五午夜前行动，国土安全部等机关资金将中断；而在期中选举将近、共和党对 ICE 与移民议题出现分裂的背景下，若停摆延长，政治反噬可能进一步加剧，压力将回到特朗普与共和党。
A fatal shooting in Minneapolis—Border Patrol agents killing ICU nurse Alex Pretti on Saturday—has sparked broad national revulsion and briefly muted the partisan reflex that usually follows major news. The episode is also reshuffling coalitions inside both parties in ways that could reshape national politics in the coming weeks and months.
The clearest sign of a potential turning point came Monday, when President Donald Trump sent border czar Tom Homan to take charge of the situation in Minnesota, effectively sidelining Homeland Security Secretary Kristi Noem and Border Patrol commander Gregory Bovino. The move is read as a possible pivot away from roaming, often-violent street sweeps tied to ICE operations in the Twin Cities—sweeps that included the detention of a masked-agents-held 5-year-old and, according to the article, the shooting deaths of two U.S. citizens: Renee Good on Jan. 7 and Pretti. The White House says Homan will report directly to Trump and is known for favoring a more targeted strategy focused on immigrants with criminal histories.
Politically, the chaos had already become a liability for Republicans, as backlash to Trump’s ICE deployment began to erode what had been his strongest issue: immigration. A Jan. 23 New York Times/Siena poll—taken before Pretti’s killing—found 63% disapproved of how ICE is doing its job, including about one in five Republicans saying it had “gone too far,” and Republican anxiety is growing ahead of November. Pretti’s death also intensified Democratic infighting, with the shock and public reaction empowering the party’s confrontational wing; moderate senators now say they won’t back Homeland Security funding without enforcement reforms like judicial warrants, clear identification in the field, and more training. With Republicans not agreeing so far, the standoff raises the prospect of another government shutdown if the Senate misses the Friday midnight deadline, and the article argues a prolonged shutdown centered on unpopular enforcement tactics could deepen GOP divisions and increase pressure on Trump as the midterms approach.
