Robert Califf is set to return to the role of US Food and Drug Administration (FDA) commissioner which he held from February 2016 to January 2017, the final 11 months of the Barack Obama administration.
A cardiologist and researcher who in recent years has backed a flavour ban on vaping products, Califf, 70, has been nominated by president Joe Biden as a “steady, independent hand” to guide the agency. Biden said he was confident Califf “will ensure that the FDA continues its science and data driven decision-making”.
