According to the BBC News, the Democratic Party's petition filed in Manhattan's Federal Court on Friday said that Republican Party candidate Trump's campaign camp accepted "gladly agreed with Russia" to win that election.
New York businessman Trump was elected president of the Democratic Party, defeating former Secretary of State Hillary Clinton.
In the United States, the investigation is going on in connection with Russia's involvement with his campaign camp. But Trump and Rasia - both sides have denied it.
US intelligence agencies have earlier said that the US presidential election results in favor of trump, that Russia has tried to try it.
The Democratic Party's National Committee Chairman Tom Perez said in a statement that the incident of hacking servers of his candidate Hillary Clinton's campaign camp was an "unprecedented hijack and a blow to democracy".
In their case, Judge Jared Kushner of the trump, Roger Stone of the Republican Campaign Camp, former campaign chairman Paul Mannafort, and Wikileaks founder Julian Assange were accused.
Before the election in 2016, news of a Democratic Party campaign hacker caught in the camp of the campaign camp in May. US detectives said that suspected Russian hackers were involved in the incident.
Before the National Convention of the Democratic Party in July, WikiLeaks leaked about 20,000 emails, which were then hacked by hackers.
The BBC wrote that many of Washington's views on the Democrats' case are seen as mere political 'stents', because the investigation is unlikely to be anything that does not come in ongoing investigations.
The Washington Post wrote that, in the US law, lawsuits against a foreign state can not be filed in general.
But the Democrats say that the rules will not work in this case, because Russia has 'hacked' on the private server.
