President Joe Biden is expected to warn Americans that Russia is conducting a "sustained effort" to undermine U.S. elections.
CNN reported that Biden would reveal the Kremlin-lead effort in remarks Wednesday. The president was expected to announce Department of Justice actions to combat Russia's covert election subversion program.
Russian state media outlet RT and American Voices were being used to launder the disinformation, the report said.
CNN said the actions were Biden's "most significant public response yet to alleged Russian influence operations targeting American voters."
Sources told the network that Social Design Agency, a Russian company, has already been sanctioned for running fake news websites in Europe.

In July, the DOJ accused an RT employee of spreading disinformation by posing as U.S. residents with 1,000 social media accounts.
Russia was also found to have conducted a misinformation campaign assisting Donald Trump's election in 2016.
Olivia Troye, a former national security adviser to Mike Pence, said that "Russia’s interference in our elections is an alarming threat to the heart of our democracy."
"Foreign powers manipulating our electoral process weakens our sovereignty, undermines public trust, and exposes us to disinformation that can tear apart the fabric of our nation, which is their goal," she added on Wednesday.
