DHS: We have evidence that twenty-one states were targeted by Russian during the 2016 election cycle, but that no vote tallies were altered. DHS did not disclose state identities, advising it was up to the states. A variety of factors made it likely that cyber manipulation of the US election system was designed to change the outcome of the election.
