US President Donald Trump issued a stern public rebuke of his coronavirus task force coordinator on Monday, calling Dr. Deborah Birx "pathetic" after she issued a dire warning over the virus's spread.

Axar.az reports citing foreign media.

"So Crazy Nancy Pelosi said horrible things about Dr. Deborah Birx, going after her because she was too positive on the very good job we are doing on combatting the China Virus, including Vaccines & Therapeutics," Trump said on Twitter, adding: " In order to counter Nancy, Deborah took the bait & hit us. Pathetic! "

Trump’s sharp denunciation of Birx comes as he continues to lag behind presumptive Democratic nominee Joe Biden in nationwide polls. A poll from the Associated Press-NORC Center for Public Affairs Research released last week showed Trump being hammered for his handling of the pandemic with under one-third of Americans supportingive his efforts.

Birx warned on Sunday that the novel coronavirus has become “extraordinarily widespread” in the US, hitting both rural and urban areas equally unlike its initial march through major urban centers earlier this year.
