Marines have moved into Los Angeles to guard a federal building after a week of protests against immigration raids, while communities across the country are preparing for demonstrations against President Donald Trump’s polices this weekend.

The appeals court issued its pause just hours after Judge Charles Breyer wrote that Trump’s “actions were illegal." The 9th Circuit Court of Appeals will hear the case on June 17.

Marines deployed to Los Angeles temporarily detained a civilian on Friday, the U.S. military confirmed after being presented with Reuters images, in the first known detention by active-duty troops deployed there by President Donald Trump.

A federal judge on Thursday might rule on whether or not the Trump administration lawfully deployed National Guard and Marine Corps troops to Los Angeles.

Protests over immigration raids have broken out in several other cities, including Chicago, New York, San Antonio and Spokane, Washington.

But Judge Charles Breyer also suggested he was unlikely at this point to restrict the use of active-duty Marines in California.
