A federal judge on Sunday extended her order preventing President Donald Trump from deploying National Guard troops to Portland, prolonging a high-stakes legal fight over the president’s authority to use military force in U.S. cities.

Following a three-day trial last week, U.S. District Judge Karin Immergut issued a preliminary injunction barring the deployment of National Guard forces from any state to Portland until at least Friday, as the court continues to deliberate on the case.

In her ruling, Immergut found that the administration’s justification for federalizing the Guard was based on “exaggerated claims of violence” in the city. She wrote that local and federal law enforcement had already contained isolated protests and that there was “no credible evidence” of widespread unrest warranting military intervention.

“This Court finds no credible evidence that, during the approximately two months preceding the President’s federalization order, protests grew out of control or involved more than isolated and sporadic instances of violent conduct resulting in no serious injuries to federal personnel,” Immergut wrote.

Immergut also ruled that the Trump administration likely violated federal law governing the mobilization of the National Guard, which permits such action only in cases of rebellion or invasion. She concluded that the unrest in Portland did not meet that legal threshold.

“Defendants have not proffered any evidence demonstrating that those episodes of violence were perpetrated by an organized group engaged in armed hostilities for the purpose of overtaking an instrumentality of government by unlawful or antidemocratic means,” the judge wrote.

The court determined that deploying the Guard under these conditions infringed upon Oregon’s state sovereignty, an argument central to the state’s lawsuit against the administration.

The injunction follows a series of escalating legal confrontations between the Trump administration and the State of Oregon. Last month, Immergut blocked the deployment of Oregon’s National Guard, prompting the administration to attempt to send troops from Texas and California instead — an effort she also halted.

The Ninth Circuit Court of Appeals temporarily lifted Immergut’s earlier order but later agreed to rehear the case en banc, reinstating the block on federal troop deployment while the matter remains under review.

With her previous orders set to expire Sunday, Immergut issued the new injunction late that night, keeping the restriction in place until Friday, when she is expected to issue a final ruling based on the trial’s full record.

The decision marks another setback for the administration’s efforts to use federal troops to address domestic unrest — a move critics argue blurs the line between civil law enforcement and military authority.
