In late November, President-elect Donald Trump filled his three top health positions for his second administration: Johns Hopkins University surgeon Marty Makary was Trump’s choice for Food and Drug Administration (FDA) commissioner; Dave Weldon, former member of the US House of Representatives, was tapped as director of the Centers for Disease Control and Prevention (CDC); and Dr. Janette Nesheiwat, a Fox News contributor and one of five New York City medical directors for CityMD, a chain of urgent care centers across the region, was named the next surgeon general.
