Sen. Bernie Sanders (I-Vt.) on Friday said he would vote against President Barack Obama’s nomination to head up the Food and Drug Administration (FDA), citing Dr. Robert M. Califf’s ties to the pharmaceutical industry.

Califf, a cardiologist and Duke University researcher, became FDA deputy commissioner earlier this year, and Obama announced plans to nominate him as the agency’s chief last month. But in light of several recent industry scandals that brought national attention to price gouging of life-saving medications, Sanders—who is running for president as a Democrat—on Friday said he would not support the status quo when the vote comes before the U.S. Senate health committee.

“At a time when millions of Americans cannot afford to purchase the prescription drugs they need, we need a new leader at the FDA who is prepared to stand up to the pharmaceutical companies and work to substantially lower drug prices. Unfortunately, I have come to the conclusion that Dr. Califf is not that person,” Sanders said following a meeting with the nominee this week.

A recent exposé by the New York Times revealed that Califf’s multi-million dollar research center at Duke received more than 60 percent of its funding from the industry, while his 2014 financial disclosure documents showed drug companies like Eli Lilly, Merck, and Novartis paid him hefty fees for “consulting” and in salary support. And as the Boston Globe reported on Wednesday, Califf also took the “highly unusual” step of removing his name from a series of scientific papers criticizing the FDA’s oversight of clinical trials—”a decision that could raise ethical concerns,” explains the Globe‘s Sheila Kaplan.
