Director of National Intelligence Coats (a Republican appointed by Trump) is concerned about Russian meddling in the 2018 midterm elections.
This article states:
“Russia is attempting to influence the midterm elections in the United States in November as well as divide the transatlantic alliance, US Director of National Intelligence Dan Coats warned at a meeting co-hosted by the Atlantic Council in Normandy, France, on June 8.
Coats said Russia had already undertaken an “unprecedented influence campaign to interfere in the US electoral and political process” in 2016. Russia, Coats pointed out, has also meddled in France, Germany, Norway, Spain, and Ukraine. “It is 2018, and we continue to see Russian targeting of American society in ways that could affect our midterm elections,” he said.”
