A cloud of uncertainty is hanging over Los Angeles, where questions remain over the role that Marines and National Guard troops will play after being called in by President Donald Trump amid protests over immigration raids in the city.

Several U.S. cities braced for protests on Wednesday against President Donald Trump's sweeping immigration raids, as parts of the country's second largest city Los Angeles spent the night under curfew in an effort to quell five days of unrest.

Protests in Los Angeles appeared to quiet overnight, but new ones are popping up in other cities. Trump has deployed more than 4,000 National Guard troops and 700 Marines to the protests.

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 Trump and Gov. Newsom.

The protests began Friday after Immigration and Customs Enforcement agents carried out coordinated raids across Los Angeles, detaining dozens of workers at warehouses and other worksites. The arrests sparked immediate backlash, with demonstrators converging outside federal buildings, blocking freeways, and in some cases clashing with police.

Gov. Gavin Newsom of California criticized President Trump’s decision to send the National Guard and the Marines to Los Angeles and asked people to “reflect on this perilous moment.”

President Donald Trump is defending his decision to send Another 2,000 National Guard troops along with 700 Marines to Los Angeles, escalating a military presence local officials and Gov. Gavin Newsom don’t want and the police chief says creates logistical challenges for safely handling protests.

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