Transcript for President Trump touts unproven drug as ‘game changer’
Dr. Jen in just a moment. Breaking news from the white house that a member of the vice president's office has now tested positive for coronavirus. And president trump in his words about a drug he said could be a game changer in coronavirus. Moments later the nation's top doctor asked about it and was offered a reality check.
