Basically every news outlet says Sunday, even the reputable GOP shillers. So until I see anything otherwise I'm assuming the date is correct.Butler says Sunday. Mitch says Friday.
It kind of matters which day if the whole argument that it must secretly be Hunter is that the family didn't leave for Camp David until Friday night.
As to the place, there have been at least two corrections on where. I will put that down to confusion in report description rather than nefarious cover up.
Its mind boggling someone going into the WH would even bring it. Are there no dogs sweeping for shit? ViP or not I wouldn't fuck with the Secret Service.
