The disagreement between President Donald Trump and California Gov. Gavin Newsom over Trump deploying state National Guard troops to Los Angeles is now being debated in court. We’ll explain how the situation developed and answer some common questions.

A temporary restraining order said the deployment of the Guard was illegal and exceeded Trump’s statutory authority.

Maj. Gen. Scott Sherman said 500 National Guard members have been trained to accompany agents on immigration operations.

The Justice Department claims California's request to limit the federal response to violent riots in Los Angeles would "countermand" the president's lawful military directives.

The high-profile Democratic governors of Illinois, Minnesota and New York defended their states' immigration policies in a Republican-led House Oversight Committee on Thursday -- weighing in on the ongoing Los Angeles protests over immigration enforcement.

McCrory said the state is put in a “precarious position” when a governor and mayor aren’t willing to work with the president.

As the military presence ramped up in Los Angeles, communities are preparing for the largest protests against Trump since he took office.

With a court decision pending on the fate of National Guard troops deployed in the city, roughly 200 U.S. Marines moved into downtown Los Angeles today to protect federal buildings amid continuing protests over ongoing immigration raids in the Southland.
