Most of the federal scientists who improperly accepted personal money from drug or biotechnology companies walked away with reprimands or were allowed to retire unscathed. Only two of the 44 scientists found to have violated rules governing private consulting deals are being investigated for possible criminal activity, and they remain on the government payroll. NIH spokesman John Burklow said his agency wanted eight others reviewed for possible crimes, but those cases were rejected by the investigating office at the U.S. Health and Human Services Department. The two still outstanding...both committed serious misconduct," so grave that they would be fired if they were civilians, NIH internal ethics reports contend. [A Congressional] subcommittee is expected to question NIH officials about documents showing it approved several taxpayer-paid trips for [Dr. Trey] Sunderland to attend conferences and events in places like Hawaii and Toronto, even after recommending his firing. Of the 44 alleged offenders...the majority received reprimands or warnings for failing to properly obtain approvals for their outside consulting work. NIH ethics reports allege...two scientists had unauthorized, unreported deals with drug companies -- Sunderland earning more than $600,000 over eight years for consulting and speeches and [Dr. Thomas] Walsh more than $100,000 in five years -- and that their consulting improperly overlapped with government duties.
