WASHINGTON — Former pharmaceutical lobbyist Jack Kalavritinos, who also worked in various capacities for the George W. Bush administration, will take a major role on the “beachhead” team that the incoming Trump administration is sending to run the Food and Drug Administration following Friday’s inauguration, transition team sources say.

Kalavritinos spent seven years as director of global lobbying for the Irish pharmaceutical and medical device company Covidien, which sells a wide array of hospital supplies around the world. The US company Medtronic bought Covidien in 2014 and promptly moved its headquarters to Ireland, which has a lower corporate tax rate.
