In this Feb. 4, 2016 file photo, pharmaceutical chief Martin Shkreli speaks on Capitol Hill in Washington during the House Committee on Oversight and Reform Committee hearing on a decision by his former company, Turing Pharmaceuticals, to significantly raise the price of the anti-parasitic medication Daraprim. Heated protests at the University of California, Davis brought the cancellation of planned speeches by far-right commentator Milo Yiannopoulos and former pharmaceutical executive Shkreli shortly before the event was to begin. University police put up barricades as protesters shouting "shut it down" grew increasingly rowdy in the hours leading up to the talks on Friday night, Jan. 13, 2017. (AP Photo/Susan Walsh, File)
