California's biggest wildfire of the year spreads to 70,000 acres
Around 200 people were ordered to evacuate, with dozens of buildings threatened by the flames.
The "Madre Fire" broke out on Wednesday in San Luis Obispo, a rural county in the heart of the US state.Trump needs to WAKE UP and start funding federal firefighters and land-management teams in these rural communities -- instead of giving tax cuts to billionaires," Newsom, a Democrat, wrote on X.
"Trump's incompetence is endangering lives."
A separate statement from the governor's press office said Friday that the Madre Fire "remains in a very isolated location -- away from homes."
It comes after several other blazes, raising fears of a difficult summer ahead for the state already traumatized by the wildfires that killed 30 people in January.
Southern California had an unusually dry winter and spring, and vegetation is already parched, UCLA extreme climate events specialist Daniel Swain has said.
Intense and widespread heat this summer, and dry brush "will heavily factor into burning conditions later this season," he added.
Since returning to the White House in January, Trump has ordered budget and personnel cuts at the Forest Service, the National Oceanic and Atmospheric Administration (NOAA) and FEMA, the federal agency that coordinates disaster response.
On Wednesday, Newsom accused the Republican president of not funding enough wildfire prevention projects.
"We need an equivalent commitment of resources -- not rhetoric," Newsom told reporters, noting that more than half of the land in California is under federal jurisdiction.
