Oregon filed a federal lawsuit Sunday against the Trump administration, challenging the planned dispatch of 200 National Guard troops to Portland as an unlawful overreach that could inflame tensions around immigration protests, even as the White House doubles down on protecting ICE facilities from what it calls domestic threats.

The suit, lodged by Attorney General Dan Rayfield, brands the move "provocative and arbitrary," warning it risks public safety by stoking outrage at a time when local leaders insist the city remains calm.

President Donald Trump, who greenlit "full force" Saturday to shield detention centers, argued the Guard would safeguard federal assets amid "siege" by Antifa and others; the Department of Homeland Security echoed this, citing doxxing of officers and death threats from the loosely organized far-left group, now labeled a domestic terror outfit by executive order.

Protests at Portland's ICE center have simmered since June, yielding 26 federal charges for arson and assaults, but Democratic officials like Governor Tina Kotek and Senator Ron Wyden decry federal meddling as a replay of 2020's George Floyd unrest playbook. "There is no national security threat," Kotek stated, while Representative Suzanne Bonamici highlighted detentions of non-threats like a father at his child's school and a wildfire fighter.

Legal scholars note Antifa lacks formal terror status, potentially inviting First Amendment fights, as seen in a California judge's recent ruling against a similar Los Angeles deployment.

Republican backers, including Labor Secretary Lori Chavez-DeRemer—a former Oregon congresswoman—praised the action to reclaim a "crime-ridden warzone." The order expands Trump's urban troop tactics, following stints in Los Angeles (deemed illegal) and Washington, D.C., with Memphis next on deck; experts question the Posse Comitatus Act's limits on military domestic roles.
