United States President Donald Trump has amplified his criticism of Dr Anthony Fauci, the nation's top infectious disease expert.
Trump retweeted several tweets that attacked the credibility of Fauci, a leading member of the White House coronavirus task force.
Later, Trump appeared to back away from his criticism of Fauci, saying, "I get along with him very well" and even appearing envious of his widespread approval rating.
"He's got a very good approval rating, and I like that," Trump said, adding that Fauci and White House coronavirus task force coordinator Dr Deborah Birx work for him.
"And yet they're highly thought of but nobody likes me. It can only be my personality. That's all."
