President Donald Trump flirted with invoking the Insurrection Act in Los Angeles as he tore into 'bad people' and 'animals' he said brought the city to the verge of burning down.

The president defended his own decision to sent U.S. Marines as well as California National Guard to Los Angeles, and brushed off California Gov. Gavin Newsom's claim that the deployment inflamed the situation.

And he would not rule out use of an authority to deploy military forces under his control to put down disturbances if he sees fit.

'If there's an insurrection, I would certainly invoke it. We'll see. But I can tell you, last night was terrible. The night before that was terrible,' Trump said.

'If we didn’t send in the national guard quickly, right now, Los Angeles would be burning to the ground,' Trump told reporters in an impromptu Oval Office meeting with members of his team.
