The Navajo Nation reports at least 15 Native Americans in Arizona and New Mexico have been stopped by immigration officers at their homes and workplaces over the past week and asked to produce proof of citizenship. The stops came as President Trump’s “border czar” Tom Homan said he plans to continue immigration raids “without apology.”

ICE says it arrested 1,179 people on Sunday — the largest number ever on a single day by either Trump administration. Over the weekend, Homan and other administration officials visited Chicago to personally oversee ICE raids that have terrorized immigrant communities. His visit came after Chicago Public Schools said it would not cooperate with ICE’s plans to conduct raids at schools. At least seven other major public school districts across the U.S. have issued similar statements.
