A live TV debate between the candidates for vice-president ahead of next month’s US election has seen fierce clashes over the coronavirus pandemic.
Democrat Kamala Harris accused Donald Trump of “the greatest failure of any presidential administration” in history.
Vice-President Mike Pence, a Republican, said her party’s pandemic plan amounted to “plagiarism”.
Democratic nominee Joe Biden leads Mr Trump with 26 days to go to the vote.
Opinion polls indicate the Republican president is trailing by single digits in a handful of battleground states that will decide who wins.
This was a civil debate between two smooth communicators compared to last week’s belligerent showdown between Mr Trump and Mr Biden, which degenerated into insults and name-calling.
Mr Pence did not interrupt as much as the president last week, but when he did Ms Harris interjected: “Mr Vice-President, I’m speaking, I’m speaking.”
Indeed the viral moment on Wednesday night that seemed to create the most buzz was a fly landing on Mr Pence’s head and remaining there for some two minutes.
But there were heated exchanges.
What was the main talking point?
In the 90-minute live debate at the University of Utah in Salt Lake City, Ms Harris accused Mr Pence and the president of deliberately misleading Americans about the lethality of coronavirus.
“They knew, and they covered it up,” she said, adding that they had “forfeited their right to re-election”.
Mr Pence accused the Biden-Harris campaign of copying the White House’s pandemic strategy, alluding to a blunder that ended Mr Biden’s 1987 run for the presidency when he plagiarised a speech by then-British Labour leader Neil Kinnock.
Ms Harris was asked by the moderator whether she would take an approved Covid-19 vaccine distributed ahead of the election.
The 55-year-old California senator said she would not take a jab touted by Mr Trump without the say-so of medical professionals.
Mr Pence, who heads the White House coronavirus task force, retorted: “The fact that you continue to undermine public confidence in a vaccine if the vaccine emerges during the Trump administration I think is unconscionable.”
The plexiglass barriers separating the two debaters seated 12ft (3.6m) apart was a vivid reminder of the pandemic that has killed more than 200,000 Americans.
The president – who is himself recovering from the virus – returned to the White House on Monday evening after three nights in hospital, with his opinion poll numbers drooping.
On Wednesday he declared that catching the disease was a “blessing from God” that exposed to him to experimental treatments he vowed would become free for all Americans.
The virus has meanwhile spread through the West Wing of the White House as well as infecting figures inside the president’s re-election campaign and senior Pentagon officials.
