A new poll shows a partisan split on President Donald Trump's troop deployment to quell Los Angeles protests, with 86% of Republicans supporting while Democrats strongly oppose it.

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.

A federal judge will hold a hearing on Thursday over California’s request to block the Trump Administration from using troops in Los Angeles to quell unrest sparked by Immigration and Customs Enforcement (ICE) raids as part of the President’s mass deportation effort.

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 Marines will take over some duties from the National Guard amid a legal battle between California and the Trump administration over the forces’ deployment.
