California Governor Gavin Newsom took to the airwaves Tuesday night — with federal troops stationed in his state’s largest city and immigration agents rounding up residents — and warned Americans that democracy itself was under attack from President Donald Trump.

Their clash over Trump’s deployment of military forces for anti-ICE protests in Los Angeles is far from the first time the two leaders have butted heads.

While protests Wednesday were relatively peaceful, some turned into scenes of chaos as police fired with less lethal munitions to the disperse crowds.
