Trump ordered the National Guard to Los Angeles to quell concrete-hurling protesters opposed to tougher immigration enforcement.

Donald Trump’s decision to order National Guard troops into the streets of Los Angeles, over the loud objections of California’s Democratic governor Gavin Newsom, is one of the most serious moments of his tumultuous presidency.

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.

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.”
