OIG had them all before phones started getting wiped, point I was trying to make several days ago:
"The OIG discovered the biased Page-Strzok texts during an inquiry into the handling of the FBI’s investigation of the Trump campaign. After the inspector general informed Mueller of the texts in late July, Mueller removed Strzok from the Russia investigation. Former FBI Deputy Director Andrew McCabe told lawmakers that he learned of the text messages on July 27 and made the decision to remove Strzok the same day. Someone wiped Page’s phone four days later."
