US President Donald Trump and Democratic rival Joe Biden debated on last night for the final time ahead of the 3 November election.
During a segment on climate change, Biden said his environmental plan would "transition from the oil industry" in favour of renewable energy sources, prompting Trump to go on the attack.
"He is going to destroy the oil industry," Trump said. "Will you remember that, Texas? Will you remember that, Pennsylvania?"
Relatively few voters have yet to make up their minds, and Trump's window to influence the outcome may be closing. A record 47 million Americans already have cast ballots, eclipsing total early voting from the 2016 election.
The contentious first debate, when the two men traded insults, was watched by at least 73 million viewers. Trump passed up another planned debate last week after it was switched to a virtual format following his COVID-19 diagnosis.
Trump trails former vice president Biden in national polls, but the contest is much tighter in some battleground states where the election will likely be decided.
