WASHINGTON: US President Donald Trump has fired top election security official, Chris Krebs who rejected his claims of fraud in the 2020 presidential polls.

In a series of tweets, Trump said that Krebs' recent statement defending the security of the recent election was "highly inaccurate."

Meanwhile, President-elect Joe Biden will meet with healthcare workers in a virtual event in Wilmington today to discuss COVID-19 surge.

Biden has pledged to make the pandemic a top priority when he takes office on 20th of January next year.
