US House Speaker Nancy Pelosi said she does not have confidence in White House coronavirus taskforce coordinator Dr Deborah Birx, linking her to disinformation about the virus spread by President Donald Trump, Reuters reports.

“I think the president has been spreading disinformation about the virus and she is his appointee so, I don't have confidence there, no,” Speaker Pelosi told ABC's 'This Week' when asked if she has confidence in Birx.

Birx, asked about Pelosi's comment during an interview with CNN's 'State of the Union', said she had great respect for Pelosi and attributed the criticism to a New York Times article on the White House pandemic response that described Birx as having embraced overly optimistic assessments on the virus.
