COVID-19 and a fly dominated the first and only U.S. vice-presidential debate.
Republican Mike Pence and Democratic challenger Kamala Harris sat behind Plexiglas shields.
Harris says President Donald Trump's handling of the pandemic is the ``greatest failure of any presidential administration.''
But Pence says Trump has constantly put the American people first.
The fly bypassed the Plexiglas and embedded itself in Pence's white hair.
Its brief stay ignited a social media frenzy with comedian Amber Ruffin tweeting "you know what flies are attracted to."
