WASHINGTON: US President Donald Trump spent time in the Oval Office on Tuesday, the day after he was discharged from hospital to continue his Covid-19 treatment at the White House, a top aide said.

"The government is functioning," White House economic advisor Larry Kudlow told CNBC on Wednesday. "The president actually showed up in the Oval Office yesterday with extra precautions, with respect to his Covid-19."

Trump has been heavily criticized over his attitude towards the coronavirus, as the number of Covid-19 cases among his inner circle rises.
