Is there a problem with the timeline with respect to the alleged Russian hack of the DNC servers?

You got Mifsud telling PappaD about the hacked emails on or about 4/26/16.  However, Julian Assange does not mention the impending leak until JUNE.  It was after this date that the DNC claimed that they were hacked.

In addition, the forensic evidence shows the data was on a mass storage device in LATE MAY.

If there was a hack, how did Mifsud know about it so soon?  Or even before the DNC knew about it?

Julian Assange hadn't even published it yet in the Wikileaks.  Nobody seems to know about it except for Mifsud.  Or have I gotten it wrong?  Here's a video showing the timeline.

Mifsud goes to Russia just prior to telling PapaD about the emails.  If Mifsud was British Intel, then the DNC was supposedly hacked prior to that date.  These dates don't match up.  Something's wrong here, boss.
