Democratic politicians have spent the last few months talking about standing up to President Donald Trump in his second term. California Gov. Gavin Newsom is among the first faced with figuring out what standing up actually looks like.

Newsom lambasted Trump, calling him a President who “wants to be bound by no law or constitution, perpetuating a unified assault on American traditions.” And he repeated his assertion that Trump was “fanning the flames” in Los Angeles “on purpose.”

The California governor and Republican president have clashed over troop deployments to quell the Los Angeles riots.
