More than a kernel of truth in that.................
The intelligence shows the terrorist attack was planned THEN they planned the protest in Egypt as a cover. The idea was to make it appear as if the terrorist are so in tune with the news they can pick up on a news story then plan and carry out an attack immediately.
That is the reason for lie about the attack being spontaneous.
When that didn't work the only alternative was to make everyone believe the attack and the protest were completely unrelated and just a coincidence they occurred at the same time.
That is why they continued with the “spontaneous” lie, so everyone would keep repeating there was no connection with the two. The lie has worked. Everyone now believes there was no connection.
With the terrorist attack being planned then the protest being planned as a cover, you move the planning for the attack back months.
It's not possible to plan an attack against a particular person, on a particular day, at a particular location months in advance without some guarantee the person would be at that particular location on that particular day. The person that guaranteed he would be there is Hillary.
