Immigration Enforcement — Week of Sep 22, 2025

The federal government took several significant immigration enforcement actions this week. The Department of Homeland Security waived dozens of federal laws — including major environmental and historic preservation statutes — to speed border wall construction in California, citing national security needs at the southern border. Separately, DHS extended its emergency immigration declaration for another 180 days, and a new presidential memorandum on domestic terrorism directed investigations into organizations connected to political violence, with threat categories that include extremism related to "migration."

This might matter because the law waiver for border construction effectively forecloses the ability of courts to review those specific decisions, which could affect the system of judicial oversight that ensures executive agencies follow environmental and procedural rules Congress has established. When laws can be waived at the sole discretion of one official without meaningful court review, it removes a check that normally protects both the public interest and the balance of power between branches of government.

There are important alternative explanations to consider. The law waiver authority was created by Congress itself and has been used by prior administrations of both parties for border construction — this is not a novel or improvised power. The administration describes the waiver as necessary to address ongoing national security challenges at the border. The emergency declaration extension and the domestic terrorism memorandum both respond to real-world conditions: border crossings and actual acts of political violence, including assassination attempts. Governments routinely use available legal tools to address security concerns, and use of broad authority does not automatically mean abuse of that authority.

However, the scale of this week's waiver — covering dozens of statutes across environmental, cultural, and administrative law — and the domestic terrorism memorandum's definitions tied to political viewpoints rather than just violent conduct deserve continued public attention. At the UN, the President claimed "zero" illegal entries for four consecutive months and referenced arrangements with El Salvador for jailing people who entered the U.S., claims that raise questions about data accuracy and whether standard legal processes for removal are being followed.
