Trump's recent attacks stem from his belief that Newsom's environmental priorities, particularly the protection of the delta smelt, have contributed to water shortages that allegedly hampered firefighting efforts in Los Angeles.
However, state officials dispute this claim. Most water used in Los Angeles does not come from Northern California but rather from local aqueducts and groundwater. Moreover, the fires' severity was compounded by high winds and smoke, not water shortages.
Trump's criticism also appears rooted in broader political and ideological differences. During his presidency, Trump pushed for policies favoring Central Valley farmers, often at the expense of ecological protections. Newsom, by contrast, has supported policies aiming to balance water use with environmental conservation.
