Arizona Secretary of State Michele Reagan released a statement Thursday saying that the U.S. Department of Homeland Security could not confirm that the Russian government tried to attack Arizona's election system.

The release said that Reagan's office met with DHS officials last week, and that's when DHS said it could not confirm a Russian hack of Arizona.

Previously, DHS had identified Arizona as one of the 21 states whose election systems were hacked, specifying that in most cases, voter information systems were not breached.

Reagan's release did not say that DHS found evidence disproving the idea of Russia trying to hack Arizona's election information, just that DHS does not have evidence proving the Russian government did attempt a hack.
