Republican Mike Pence and Democrat Kamala Harris have begun facing off in what is their only vice presidential debate in the US election campaign.
The candidates are separated by plexiglass barriers in an auditorium in Utah where any guest who refuses to wear a face mask will be removed.
Mr Pence and Ms Harris began by sparring over the Trump administration’s handling of the coronavirus, a point that highlighted the parties’ sharply conflicting visions for a nation in crisis.

In response, Mr Pence commended Mr Trump’s decision to shut off travel from China, saying the decision “bought us invaluable time” to coordinate the country’s response to the pandemic, although Mr Trump’s move only cut off some travel from China, and tens of thousands of people were still allowed to pour into the country.
More than 210,000 Americans have died during the pandemic. Mr Trump is recovering at the White House from his own infection.
