Donald Trump was challenged by Californian officials about his earlier comments that bad forest management, rather than climate change, was to blame for the wildfires along the US West Coast.

Democratic presidential candidate Joe Biden called Mr Trump’s denial of climate change "unconscionable", saying these "hellish events" will become more frequent if he wins a second term.
