THE Democratic National Committee (DNC) is suing Donald Trump’s campaign, his son, his son-in-law, the Russian Federation and WikiLeaks, claiming they conspired to help Trump win the 2016 US presidential election.

The DNC filed the lawsuit yesterday in the federal court in Manhattan. It seeks unspecified damages and an order to stop further interference with their IT systems.

The lawsuit claimed Trump and his associates had relationships with Russia that enabled the creation of a Trump-Russia conspiracy.

The DNC said Russia “mounted a brazen attack on American democracy”, beginning with a cyber attack on its computers. It said the hack penetrated DNC computers and phone systems and extracted tens of thousands of documents and emails.

Trump has said repeatedly there was no collusion between his campaign and Russia.

DNC chairman Tom Perez said in a statement: “During the 2016 presidential campaign, Russia launched an all-out assault on our democracy, and it found a willing and active partner in Donald Trump’s campaign.”

He called it an “act of unprecedented treachery”.

The lawsuit also accuses Donald Trump Jr of secretly communicating with WikiLeaks, saying the pres-ident’s son was offered a password to an anti-Trump lawsuit in one exchange.

The lawsuit blames the president too, saying he praised the illegal dissemination of DNC documents throughout the autumn of 2016, making it a central theme of his speeches. It also says said Trump’s son-in-law Jared Kushner was part of the conspiracy as a senior adviser and key decision-maker in the campaign.

It said he began in June 2016 to control all campaign data-driven efforts including hiring Cambridge Analytica, the controversial data firm.

The lawsuit said the conspiracy “inflicted profound damage upon the DNC”, and added: “The conspiracy constituted an act of previously unimaginable treachery: the campaign of the presidential nominee of a major party in league with a hostile foreign power to bolster its own chance to win the presidency.”
