Three of the nation's top intelligence officials say the US has seen Russian activity aimed at meddling in the upcoming midterm elections.
CIA Director Mike Pompeo said Moscow's intention is to have an impact on the next election cycle.
National Intelligence Director Dan Coats and Adm. Mike Rogers, the head of the National Security Agency, agreed.
They didn't describe the activity, other than to say it was related to information warfare.
They told members of the Senate intelligence committee Tuesday that they would provide more details in closed session.
The intelligence officials say the information will be shared with state and local governments and state election officials and that the US has to come up with ways to punish and prevent foreign meddling in US elections.
