WASHINGTON -- The heads of the lead U.S. intelligence agencies warned that Russia intends to use cyberattacks, more propaganda, and other tactics to try and influence upcoming elections for the U.S. Congress and in some European countries.

Testifying before the Senate Intelligence Committee on February 13, the directors of the CIA, the FBI, the National Security Agency, and three other spy agencies all agreed with the assessment that Moscow had not curtailed its efforts to influence U.S. politics since the 2016 presidential election.

"Throughout the entire community, we have not seen any evidence of any significant change,” Dan Coats, the director of national intelligence, told lawmakers.

"Persistent and disruptive cyberoperations will continue against the United States and our European allies using elections as opportunities to undermine democracy," Coats said in written comments.

In a report released in January 2017, U.S. intelligence agencies concluded that Russia engaged in a hacking-and-propaganda effort aimed at swaying the 2016 vote.

Moscow has repeatedly denied the accusations.

Three different congressional committees are investigating either that campaign, or suspicious interactions between Russian officials and current and past associates of President Donald Trump.

An FBI-led criminal investigation into that question has resulted in the indictments of two former associates and guilty pleas from two others.
