Trump sticks by discredited hydroxychloroquine
US President Donald Trump has again defended the use of hydroxychloroquine to ward off coronavirus, contradicting his own public health officials.
He said the malaria medication was only rejected as a Covid-19 treatment because he had recommended its use.
His remarks come after Twitter banned his eldest son for posting a clip promoting hydroxychloroquine.
There is no evidence the drug can fight the virus, and regulators warn it may cause heart problems.
Last month, the US Food and Drug Administration (FDA) cautioned against the use of the drug for treatment of the coronavirus, following reports of "serious heart rhythm problems" and other health issues.
The FDA also revoked its emergency-use authorisation for the drug to treat Covid-19. The World Health Organization (WHO) says "there is currently no proof" that it is effective as a treatment or prevents Covid-19.
