California Democratic Governor Gavin Newsom has expressed concern for the privacy of immigrants in his state, following reports that the Trump administration has shared Medicaid data with immigration officials.

Gavin Newsom (D) warned in a primetime address Tuesday amid President Donald Trump’s military response to the Los Angeles protests that this “assault” on democracy will spread across the country if Trump continues to go unchecked.

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.
