Homeland Security Secretary Kristi Noem issued a blunt ultimatum Tuesday to Portland Mayor Keith Wilson, warning that the Biden administration’s legal battles with the city won’t stop her from sending “four times the amount of federal officers” if local officials continue to resist cooperating with federal security operations.

Noem flew to Portland to tour the city’s U.S. Immigration and Customs Enforcement facility — a flashpoint for repeated protests — amid an ongoing legal dispute between Oregon state leaders and the Trump administration over the president’s plan to deploy National Guard troops to the city.
