An escalating clash pits a Republican president looking to fulfill his mass deportation goals against a Democratic governor with White House aspirations hoping to mobilize opposition.

The state of California had sought to stop the president from sending National Guard troops without the governor’s approval.

Hours after a federal judge sided with Gov. Gavin Newsom over Donald Trump's deployment of the National Guard in Los Angeles, an appeals court has blocked the ruling.

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.”

California Gov. Gavin Newsom said anti-ICE protesters in Los Angeles who engage in violence will be prosecuted to the fullest extent of the law.

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.

The public fight between California Gov. Gavin Newsom and President Donald Trump keeps intensifying, with name calling, insults and accusations traded over television and social media networks.

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