Donald Trump’s nominee for Health and Human Services secretary, Georgia Congressmember Tom Price, invested thousands of dollars in a medical device maker shortly before introducing a bill to benefit the company. That’s according to CNN, which reported Monday that Rep. Price purchased shares of Zimmer Biomet last March—less than a week before introducing the HIP Act. The legislation would have delayed regulations sure to cut into the company’s profits. Senate Minority Leader Chuck Schumer this week called for the Office of Congressional Ethics to investigate whether Rep. Price violated the STOCK Act, which restricts insider trading by members of Congress.
