Oregon Second District Congressman Greg Walden threatened to subpoena the Drug Enforcement Administration to get documents his Energy and Commerce Committee has been requesting as part of their investigation into alleged opioid pill dumping by major drug companies, including a specific inquiry into the shipment of nine million highly addictive opioid painkillers to a rural town of less than 400 people.  The Hood River Republican made the statement while questioning DEA Deputy Assistant Administrator Neil Doherty, with Walden pointing out they’ve received some of the documents they asked for from an outside source but not the agency itself.  Doherty said they would make every effort to expedite the information the committee wants.  Walden said the committee received the documents from an anonymous source, and bipartisan staff members are now reviewing them.
