As has been the case with other high-profile cabinet picks, Donald Trump appears to be considering at least one figure who is highly unconventional and distrusted by the establishment for the head of the FDA.

NBC reports Trump is pondering Jim O’Neill, who is a longtime colleague of PayPal billionaire Peter Thiel, a major Trump backer. O’Neill, like Thiel, describes himself as a libertarian and has said the FDA should have far less ability to restrict new drugs from entering the market before their safety and effectiveness has been judged.

Even the pharmaceutical industry would likely be skeptical of a vehemently anti-regulation FDA chief, says Michael Gaba, who works on health care policy for Holland & Knight, in an interview with NBC.
