Gov. Gavin Newsom’s lawsuit over President Trump’s deployment of the Marines and National Guard to Los Angeles could influence how future presidents respond to domestic unrest.

California has challenged the administration’s move to call up the National Guard over the objections of Governor Gavin Newsom.

Newsom filed a lawsuit Monday in response to Trump ordering the deployment of roughly 4,000 National Guard members to Los Angeles following protests over his stepped-up enforcement of immigration laws. They were originally called in to protect federal buildings, and the president later ordered the deployment of 700 Marines.

A majority of North Carolina swing voters in our latest Engagious/Sago focus groups supported President Trump's deportations and activation of the National Guard and Marines in Los Angeles, despite some concerns about civil rights and government overreach.

California Gov. Gavin Newsom had sued Trump in an attempt to block the deployment of federal troops in the city, which Newsom has called a “serious breach of state sovereignty.”

What the judge rules, and the likely appeals that follow, may alter decades of understanding about the roles of governors and the White House in quelling domestic unrest.

Some polls suggest Trump's clashes with Elon Musk and aggressive response to immigration protests in Los Angeles have not weakened his standing.

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.
