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 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.

Newsom said he believed the president was required to coordinate with the state’s governor before ordering such a deployment.
