SAN FRANCISCO, Oct. 4 (Xinhua) -- A federal judge in the U.S. state of Oregon on Saturday temporarily blocked the deployment of 200 National Guard troops to Portland, the state's largest city.

Karin J. Immergut, judge for the District of Oregon, issued a two-week temporary restraining order after Oregon and Portland filed a lawsuit on Sept. 28.

The lawsuit seeks to immediately block the implementation of the memorandum from Defense Secretary Pete Hegseth on the same day, which ordered the federalization and deployment of the Oregon National Guard to Portland.

In her ruling, Immergut noted that President Donald Trump's attempt to federalize the National Guard without constitutional authority infringes upon Oregon's sovereign rights.

"This country has a longstanding and foundational tradition of resistance to government overreach, especially in the form of military intrusion into civil affairs," Immergut, an appointee of Trump, wrote in her order.

"This historical tradition boils down to a simple proposition: this is a nation of Constitutional law, not martial law. Defendants have made a range of arguments that, if accepted, risk blurring the line between civil and military federal power -- to the detriment of this nation," she wrote.

A federal judge in the U.S. state of California ruled early last month that the Trump administration's deployment of the National Guard and Marines in Los Angeles in June was illegal. Enditem
