In a letter Kennedy addressed concerns raised by Senator Elizabeth Warren about his plan to keep 10-percent of any fees gained from his invovlement with lawsuits against drug makers. The president’s choice to head the Health and Human Services department says he has amended his ethic agreement so that he will not keep any of the fees.
