President Donald Trump said he would support arresting California Gov. Gavin Newsom and called the rioters in Los Angeles 'insurrectionists.'

'I would do it,' the president said when asked about Newsom daring his administration to arrest him.

'I like Gavin Newsom, he's a nice guy but he's grossly incompetent, everybody knows it,' the president added.

Trump had even harsher words for the demonstrators.

'The people that are causing problems are professional agitators and insurrectionists,' he told reporters on the South Lawn of the White House. 'They're bad people. They should be in jail.'
