Gavin Newsom won praise on Wednesday for his speech Tuesday night seen by a national audience, something many Democrats saw as a shot across the bow to President Donald Trump that they can fight Trump -- and one that sparked new talk of Newsom as the party's standard-bearer in 2028.

President Donald Trump has mobilized more than 4,000 National Guard troops and 700 Marines to Los Angeles, setting up a clash with Gov. Gavin Newsom.

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.

Gavin Newsom depicted the federal military intervention in Los Angeles as the onset of a much broader effort by Trump to overturn political and cultural norms at the heart of the nation’s democracy.

"Come and get me, tough guy. I don't give a damn," Newsom said after saying border czar Tom Homan had threatened to arrest him for speaking out on ICE raids.

Newsom is widely viewed as a likely presidential candidate. A new video shows the Democrat fashioning himself as leader of the Trump resistance.

Border czar Tom Homan has warned that anyone who interferes with ICE raids could face federal charges, including elected officials.

The California governor has clashed with Trump in recent days over the president's deployment of the National Guard to quell protests in Los Angeles.
