A congressional investigation found the NFL tried to improperly influence a government brain research study conducted by the National Institutes of Health.
According to a 91-page congressional report, obtained by ESPN's Outside the Lines, "at least a half-dozen top NFL health officials" ran an improper campaign last year in an attempt to influence a study on football's effects on brain disease.
The congressional report says the league pressured the NIH into taking the $16 million study away from a prominent researcher Robert Stern of Boston University, then "tried to redirect the money to members of the league's committee on brain injuries.
