About 700 Marines and more than 4,000 National Guard have been deployed at the cost of $134 million. William Deverell is a professor of history at USC’s Dornsife College of Letters, Arts and Sciences.

A federal judge issued a temporary restraining order Thursday directing President Donald Trump to return control of the National Guard to California.

U.S. Attorney Bill Essayli said at least nine people face federal charges related to the demonstrations. The protests have been prompted by Immigration and Customs Enforcement sweeps spurred by President Trump's directive to find immigrants living in the United States without legal status.

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.

President Donald Trump's deployment of the National Guard to Los Angeles in response to immigration protests is the latest in a long history of U.S. elected officials sending troops in hopes of thwarting unrest connected to civil rights protests.

Harris said the deployment is "part of the Trump Administration's cruel, calculated agenda to spread panic and division."

U.S. Marines will join National Guard troops on the streets of Los Angeles within two days, officials said on Wednesday, and would be authorized to detain anyone who interferes with immigration officers on raids or protesters who confront federal agents.

The curfew, which Los Angeles Mayor Bass expects to last for several days, is part of the city's strategy to quell ongoing looting and vandalism.
