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 about immigration protests that roiled Los Angeles during the weekend.

President Donald Trump on Monday stirred the already contentious riots in Los Angeles when he advocated for the arrest of California Gov. Gavin Newsom. While addressing reporters, Trump was asked if border czar Tom Homan should follow through on Newsom’s dare to arrest the California governor.

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.”
