FDA Trying to Tarnish a Whistleblower?

After challenging Food and Drug Administration policies that he claims leave the public "virtually defenseless" against questionable drugs, FDA drug safety official Dr. David Graham contacted the Government Accountability Project, a non-profit organization that protects whistleblowers. Shortly afterwards, anonymous callers to GAP charged Dr. Graham with "scientific misconduct" and being a "bully." After further research, GAP concluded that "the callers were trying to smear [Graham]." In addition, GAP's legal director said he's "certain [the anonymous callers] were supervisors at the FDA because of the details of the arguments they made and the phone numbers from which they called."
