Stephen Breyer's brother Charles Breyer will preside over the lawsuit Newsom brought against the Trump administration in California.

President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

In a federal lawsuit, California's governor argues that the president's federalization of "the State's militia" is illegal and unconstitutional.

The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

Protests surrounding immigration enforcement actions in the Los Angeles area and the Trump administration's response to them have cued up a public spat between President Donald Trump and Gov.

Defense Secretary Pete Hegseth on Tuesday defended the administration's mobilization of the National Guard and members of the Marine Corps to Los Angeles amid ongoing immigration protests.

4:47 p.m. EDT The Trump administration asked the judge to reject Newsom’s request and allow it to respond by Wednesday, calling Newsom’s attempt to block the deployment of federal troops “legally meritless” and saying it would jeopardize the safety of Homeland Security personnel and interfere with the government’s ability to carry out operations.

Dozens arrested in Los Angeles as anti-ICE protests turn violent, with charges including assault on police and attempted murder as National Guard troops deploy.
