Trump says wildfires in California began because 'trees just explode'

US President Donald Trump recently said that the wildfires in California began because "trees just explode". "When trees fall down, after a short period of time, about 18 months, they become very dry. They become, really, like a matchstick. And they get up...there's no more water pouring through, and they become very, very— well, they just explode," Trump added.
