Oh for goodness sake...
They simply were following protocol, the President has the right to reserve his communications with his executives.... he has executive privilege, to retain his communications, until a certain time, all dictated by law.
Obama could have chosen to release them early, but was probably advised by his legal team not to, because this could open up demands for other executive communications to be released before the legal time already established, lessening the executive power.
Shortly after Hillary's team notified Obama on his emails, Obama came out and told the public her emails would be released with the exception of his, which fall under his executive privilege...
So this bombshell is NO BOMBSHELL, we've all known for over a year Obama held back from the public, his emails with HILLARY.....the Wikileaks just shows how the executive privilege process works behind the scenes.....
