The complaint, which is filed in a federal district court in Manhattan, alleged that top Trump campaign officials had conspired with the Russian government and its military spy agency to hurt the Democratic presidential nominee Hillary Clinton.
President Donald Trump's re-election campaign is slamming a lawsuit filed by the national Democratic Party as "frivolous" and a "last-ditch effort to substantiate" what it says are "baseless" allegations of Russian collusion.
Defendants in the lawsuit include three people who have been indicted as a result of Special Counsel Robert Mueller's investigation of Russian meddling: former campaign chairman Paul Manafort, Manafort associate Rick Gates and former campaign aide George Papadopoulos.
Further, the Democrats have accused Trump's campaign of being "a racketeering enterprise" that worked with the Russians and WikiLeaks in a conspiracy that included hacking email servers at the DNC and leaking damaging information to the public.
Nations have immunity from most U.S. lawsuits, but the Democratic National Convention complaint argues this doesn't apply to Russian Federation because the alleged hack constitutes trespass on a private property.
The hacking of the DNC has always been a sore spot for Democrats across the board since Clinton's stunning loss in November 2016.
Russian state hackers are "targeting internet infrastructure"
Washington and London have detailed how Russian-backed hackers have been compromising network devices around the world since 2015.
Trump's campaign and the Republican National Committee did not immediately respond to the lawsuit. "Through multiple meetings, emails, and other communications, these Russian agents made clear that their government supported Trump and was prepared to use stolen emails and other information to damage his opponent and the Democratic Party". In response, Trump and his administration quickly denied any wrongdoing, claiming there was "no collusion" between himself and the Kremlin.
What do you think of the DNC lawsuit against Trump?
"We're taking this action because we believe no one is above the law, and we must pursue every avenue of justice against those who engaged in this illegal activity against the DNC and our democracy", he said.
It said the hack penetrated DNC computers and phone systems and extracted tens of thousands of documents and emails. According to them, the hacker attacks have reduced the ability of Democrats to communicate with voters, raise donations and to operate efficiently, the newspaper said.
Trump among the defendants is not specified, it lists only the persons of his entourage.
