Kavangaugh's calendar supports Ford's testimony

According to this report, it even suggests the date of the assault was July 1, 1982. Mitchell, the hit woman the Repugs hired, questioned Kav on that particular calendar entry where it lists who was present at the event on that date. It corroborates Ford's testimony on who was in attendance at the party where she was assaulted. Again, will this be investigated by the FBI?
