The U.S. Department of Justice ended Monday its prosecution into a Russian firm that was charged by then-Special Counsel Robert Mueller for interfering in the 2016 election through coordinated social media campaigns, Concord Management, The Washington Post reported.

In their motion to dismiss the case, Assistants to U.S. Attorney Timothy Shea of Washington D.C., and Assistant Attorney General for National Security John C. Demers wrote, “Upon careful consideration of all of the circumstances, and particularly in light of recent events and a change in the balance of the government’s proof due to a classification determination, as well as other facts described in more detail in a classified addendum to this motion, the government has concluded that further proceedings as to Concord, a Russian company with no presence in the United States and no exposure to meaningful punishment in the event of a conviction, promotes neither the interests of justice nor the nation’s security.”

The trial was set for April 6.
