There have been claims made by a rogue section of the CIA, stating that the Russians influenced the election, in which Donald Trump beat out Hillary Clinton.
However, they do not have any proof to back up these claims. That does not hinder their persistence for a new election though. They can try to convince people that they are correct, and that there NEEDS to be a new election. This could cause those people to become violent when Trump does not accept these bogus terms.
