McKinsey & Company worked on 37 FDA contracts while simultaneously consulting for Purdue Pharma on strategies to boost OxyContin sales, a massive conflict of interest they never disclosed to the FDA. McKinsey used its government work to solicit business from opioid manufacturers and tried to influence Trump HHS Secretary Alex Azar for private opioid clients. In July 2018, senior partners discussed destroying their Purdue documents, with one emailing himself a note to 'delete old pur documents from laptop.' McKinsey paid $650 million to resolve criminal and civil investigations.
