Members of Congress have been drawing attention to conflicts of interest between biomedical researchers whose research is useful to companies that pay them to consult. Jonathan Gruber, a health economist at the Massachusetts Institute of Technology, is facing a different kind of allegation, The Boston Globe reported. He has been speaking with reporters about the health care legislation before Congress without disclosing that he is a paid adviser to the Obama administration on the legislation. He told the Globe that he didn't think his ties were an issue and that he disclosed them whenever asked.
