President Donald Trump said on Monday he would support the arrest of California's Gavin Newsom, in a dramatic escalation of a growing conflict with the Democratic governor over immigration protests that roiled Los Angeles over the weekend.

Newsom plans to file suit against the Trump administration to roll back the National Guard deployment, which he called “an illegal act, an immoral act, an unconstitutional act.”

Newsom filed suit against the White House on Monday over its decision to deploy the National Guard. California Attorney General Rob Bonta says the state’s sovereignty was “trampled” by President Donald Trump when he ordered National Guard troops to the immigration protests in Los Angeles, The Associated Press reported.
