This isn't the first time ISIS has issued a threat directly toward The White House. In a stunning documentary by Vice News from inside "The Islamic State," the group's press officer Abu Mosa said they would "raise the flag of Allah in The White House."

In the same documentary, he also said the group would "liberate" Istanbul if the Turkish government didn't reconsider its decision to go against them. Mosa was later killed by an airstrike in Syria.
