The Supreme Court ruled 6-3 on June 26, 2026, allowing the Trump administration to turn away asylum seekers at the U.S.-Mexico border — expanding the executive's power to regulate asylum access without Congressional approval. The same decision also allowed the administration to end Temporary Protected Status (TPS) for Haitian and Syrian nationals, potentially opening the path for hundreds of thousands of deportations. Immigration advocates warned the ruling will harm vulnerable populations, while the Trump administration has long sought these legal authorities as central to border management policy.
