The president was not named in the suit, in which Democrats said, "Russia mounted a brazen attack on American Democracy" with a cyberattack on the Democratic National Committee’s servers.
"In 2015 and 2016, Russian intelligence services hacked into the DNC's computers, penetrated its phone systems and exfiltrated tens of thousands of documents and emails," according to the lawsuit.
"Russia then used this stolen information to advance its own interests: destabilizing the U.S. political environment, denigrating the Democratic presidential nominee and supporting the campaign of Donald J. Trump, whose policies would benefit the Kremlin. In the Trump campaign, Russia found a willing and active partner in this effort."
Democrats said the stolen data was shared with WikiLeaks founder Julian Assange, who released thousands of emails last year that were allegedly taken in a hack of the DNC's servers. The lawsuit alleged Assange shared the emails because he “shared the defendants’ common goal of damaging the Democratic party in advance of the election.”
Assange said in late 2016 that his source for the DNC emails “was not the Russian government.” The Kremlin has denied any involvement in the hack.
Democrats did not mention in their lawsuit that FBI officials warned the DNC that it was being hacked or that officials at DNC headquarters in Washington ignored the warning for weeks, Cox Media Group’s Jamie Dupree reported.
The suit seeks millions of dollars in damages, as Democrats said the hacks hindered the party's ability to communicate with voters or effectively operate, according to the Post.
Officials, including special counsel Robert Mueller, continue to investigate whether people who worked on Trump’s 2016 presidential campaign worked with Russian government officials to sway the election. Trump has repeatedly denied collusion allegations. The Kremlin has denied that officials meddled in the election.
