Still, officials warned that foreign efforts to interfere in U.S. elections continue.

“Americans should be aware that foreign actors — and Russia in particular — continue to try to influence public sentiment and voter perceptions through actions intended to sow discord,” the statement said. “They can do this by spreading false information about political processes and candidates, lying about their own interference activities, disseminating propaganda on social media, and through other tactics.

“The American public can mitigate these efforts by remaining informed, reporting suspicious activity, and being vigilant consumers of information.”

Voters on Tuesday will elect a new House of Representatives and vote in 35 U.S. Senate elections. In 36 states, governors will be elected.
