Covid-19: President Trump's doctor 'extremely happy' with progress

Donald Trump's personal physician has told reporters he's "extremely happy with the progress the president has made" after starting treatment for Covid-19.

Dr Sean Conley and other doctors from Mr Trump's medical team spoke from outside Walter Reed Army Medical Center in Washington on Saturday morning.

They said he was doing "very well" and in "exceptionally good spirits".

However, their account was later disputed.
