President-elect Donald Trump and California Gov. Gavin Newsom clashed Wednesday over fires burning out of control in the Los Angeles area, injecting national politics into a growing crisis in the city that Vice President Kamala Harris calls home and that President Joe Biden was visiting for the birth of his great-grandson.

Donald J. Trump issued angry comments about Gov. Gavin Newsom, and President Biden was briefed in California by the state’s fire officials.

The president-elect blamed California Governor Gavin Newsom for the massive fires that have forced tens of thousands to evacuate, saying the governor should have signed a declaration to pump more water through the state.
