"We will work with law enforcement if they are involved but we will also continue our own investigations and working cooperatively with everyone to make sure that we are taking this seriously, that we find out the conclusions," Goodell continued. "When we find out the facts we will share them, as we have in the past. We will want to make sure that we are transparent. We do not have an independent investigation going on at this point, other than working with the other leagues and with WADA. If we feel that that's necessary at some point, we may do that. At this point, we don't."
