CALIFORNIA TAKEOVER: Gov. Gavin Newsom is asserting himself on the global climate stage just as President Donald Trump and the United States are retreating on climate change. The governor and a Golden State delegation are in Brazil this week at the annual climate summit known as COP30.

However, more and more psychologists have started to agree with Newsom's dementia diagnosis. Dr. John Garner, who co-hosts the Shrinking Trump podcast, said Trump's confusion, bizarre and incoherent rambling, and memory lapses are signs of "immense cognitive decline."

California Gov. Gavin Newsom, in an interview with ABC's Jonathan Karl, said he is "deeply concerned" about President Trump and his allies comments on a third term.

California Governor Gavin Newsom (D) went off on President Donald Trump's nuclear testing announcement in an upcoming interview with Meet the Press.

Newsom is not the first California governor to fill the U.S. seat at international climate talks when Washington interest wanes. His Democratic predecessor, Jerry Brown, got a warm greeting at the U.N. climate talks in 2017, during Trump’s first term.

Gov. Gavin Newsom (D-Calif.) tells Meet the Press in an exclusive interview that “the rules of the game have changed” in facing off with President Trump and says he is “deeply confident” that a measure that would allow the state to move forward with mid-cycle redistricting will succeed.

Gavin Newsom (D) has hurled yet again sharp criticism at President Donald Trump after the Democrats’ recent election sweep. While speaking at a rally in Houston, Texas, on Saturday, the governor mocked his political foe as an “invasive species” while declaring that Trump had a “very bad night” on Nov.

Newsom kicked off his trip to Brazil 1,800 miles south of the Amazonian city of Belém that’s hosting this year’s international gathering, talking to Brazilian and American financiers at an investors' summit in São Paulo.
