Supporters hospitalized following rallies in Las Vegas and Phoenix, where temperatures have broken records

Dozens of Donald Trump’s supporters have been requiring medical help at his rallies in the scorching US south-west but it seems lost on him that his plans to reverse climate policies and “drill, baby, drill” for fossil fuels will only worsen extreme weather, campaigners say.

A total of 24 people at a Trump rally in Las Vegas on Sunday required medical attention due to the heat, according to the Clark county fire department, with six taken to hospital for treatment. The hospitalizations come after a further 11 people needed to be admitted to hospital for heat exhaustion as they waited for Trump to speak at a rally in Phoenix on Thursday.
