The comments may no longer visible, but if you notice one poster was accusing admin of deleting his/her comment and then taking credit for "discovering" the timeline. The admin then says he had the timeline since 1/12 but did not release it because TR was waiting for approval from the state police.
Admin of the FB further states that TR and camp were accusing him of leaking the timeline, because they saw it appearing on sites like Hinky Meter. Admin of the FB also said that the person running aylareynolds.com did not know that the timeline was accessible online so he removed it. That indicates that the timeline was NOT approved; otherwise TR would have published it herself instead of accusing someone of "leaking" it. The timeline was quite heavily revised, and then released because it was already starting to circulate.
I do not have screenshots, but if you followed the page then you know exactly what I'm talking about. You can still see the poster (with no pic) who posted the unedited timeline, and then later states that he/she "stands corrected".
