Trump is now being treated with steroid; doctors monitoring his lungs

The medical team treating President Donald Trump for Covid-19 is monitoring the condition of his lungs after he received supplemental oxygen on Thursday and Friday, but declined on Sunday to provide details of what they had seen.

Trump, 74, who was flown to Walter Reed National Military Medical Center on Friday, has taken two doses of a five-day course of the intravenous antiviral drug Remdesivir, as well as the steroid dexamethasone, which is used in critical cases.

Dr. Sean P. Conley acknowledged that Trump's blood oxygen levels had dropped in prior days and that he had run a high fever on Friday
