The deployment of troops to Los Angeles raises questions about what Trump can and can't do with the military on U.S. soil, and whether he's crossing the line.

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

Georgia Washington University law professor Jonathan Turley said on Fox News Wednesday that California’s legal challenge to President Donald Trump and his decision to deploy National Guard troops to that state is “very weak.

Trump calling the National Guard into Los Angeles should "give every American chills," a former federal prosecutor told Newsweek.

Protesters clashed with law enforcement in Los Angeles on Sunday after Trump deployed National Guard troops over the objections of Gov. Newsom.

California Governor Newsom has sounded the alarm over President Trump’s deployment of troops to Los Angeles, calling it a dangerous step toward military-backed immigration crackdowns nationwide. He warned that what’s happening in California could soon spread to other states.

Gov. Gavin Newsom told POLITICO that federal law requires President Donald Trump to coordinate his call-up of the National Guard with the state.

The state’s attorney general argued that local law enforcement had been capable of handling the situation and could have requested support from state partners had it been necessary.

A federal court hearing is scheduled on whether the Trump administration can use the National Guard and Marines to assist with immigration raids in Los Angeles
