California Gov. Gavin Newsom: Donald Trump is not only temporary, but he may be among the most un-American presidents ever to have resided at 1600 Pennsylvania Avenue. He’s an invasive species. He’s taken over the Republican Party. Ronald Reagan would be ashamed of this moment in time. Those values are being vandalized in real time. Our republic is being vandalized in real time. Every day, we’re fighting the fight to save our republic.
