Heated disagreement breaks out in Situation Room over hydroxychloroquine

There was a heated disagreement in the Situation Room this weekend over the efficacy of the anti-malaria drug hydroxychloroquine but multiple sources say it was mostly one-sided, as President Donald Trump's top trade adviser Peter Navarro feuded with other officials over the drug's unproven effectiveness to treat coronavirus.

The debate is not a new one inside the coronavirus task force -- and medical experts have repeatedly explained to the President that there is a risk in enthusiastically touting hydroxychloroquine in case the drug doesn't ultimately work to combat the virus. But other aides and outside advisers have sided with Trump, including Navarro, who is still not a formal part of the task force but has wedged himself into the meetings.
