Russian interference in the 2018 United States elections

The United States Intelligence Community concluded in early 2018 that the Russian government was continuing the interference it started during the 2016 elections and was attempting to influence the 2018 United States mid-term elections by generating discord through social media. Primaries for candidates of parties began in some states in March and would continue through September. The leaders of intelligence agencies have noted that Russia is spreading disinformation through fake social media accounts in order to divide American society and foster anti-Americanism.

In 2022, it was reported that a Federal Election Commission investigation had found that American Ethane Company, which had received investments from Russian oligarchs, had contributed Russian money to US political candidates in the 2018 midterm elections, largely in Louisiana. FEC commissioners Ellen Weintraub and Shana M. Broussard criticized the Republicans in the FEC for a "slap on the wrist" civil penalty.

In testimony before the Senate Intelligence Committee on February 13, Coats noted that voting in some elections will begin as early as March 2018 for primaries. He stated: "We need to inform the American public that this is real, that this is going to happen." At the same hearing, CIA Director Mike Pompeo told the committee that Russia has already been observed engaging in such tactics.
