Wyoming's grizzlies have met the delisting criteria under the ESA, so why are they still listed?

During today's hearing with U.S. Fish and Wildlife Service Director Williams, I asked why Wyoming's grizzly bear population is still listed as endangered, despite having long ago met all criteria for delisting. She was not able to respond, stating that they were "working on a 12-month" review process. Yet despite multiple questions, she was unable to say when the review began, when it would end, or even how long it would actually last.
