Native American organisations and Democratic governors staged coordinated Indigenous Peoples' Day events across the United States on Monday, challenging President Donald Trump's rollback of tribal consultation protections. The largest gathering took place in Washington near the National Museum of the American Indian.

The demonstrations occurred as the federal government shutdown entered its second week, with hundreds of thousands of federal workers furloughed and data releases suspended. Trump restored the official Columbus Day designation earlier in his term, reversing President Joe Biden's dual recognition of Indigenous Peoples' Day.

The National Congress of American Indians said it would press the administration over frozen funding to the Indian Health Service and the Bureau of Indian Affairs, both affected by the lapse in appropriations. Democratic governors including New Mexico's Michelle Lujan Grisham issued state proclamations recognising Indigenous Peoples' Day in defiance of federal messaging.

Republican leaders in Congress framed the holiday around Italian American heritage, while the White House issued a Columbus Day proclamation celebrating exploration. The competing observances reflected the cultural divide sharpening the standoff in Washington as neither party showed signs of ending the shutdown.

A National Congress of American Indians spokesperson said: "Tribal nations cannot afford a government that treats our treaty obligations as optional." The organisation called for the immediate release of withheld health funding.
