• The Democratic National Committee sued the Trump campaign, the Russian government, Wikileaks on Friday, accusing them of conspiring to disrupt the 2016 presidential election.
  • President Donald Trump’s son Donald Trump Jr. and son-in-law Jared Kushner are among the defendants.
  • The DNC says Russia found a “willing and active partner” in the Trump campaign to attack American democracy and defeat Hillary Clinton.

The Democratic Party on Friday sued President Donald Trump’s presidential campaign, the Russian government and the Wikileaks group, claiming a broad illegal conspiracy to help Trump win the 2016 election.

The multimillion-dollar lawsuit filed in Manhattan federal court says that “In the Trump campaign, Russia found a willing and active partner in this effort” to mount “a brazen attack on American Democracy,” which included Russian infiltration of the Democratic Party computer network.

The Trump campaign, according to the lawsuit, “gleefully welcomed Russia’s help.”

The suit says that “preexisting relationships with Russia and Russian oligarchs” with Trump and Trump associates “provided fertile ground for [the] Russia-Trump conspiracy.”

The common purpose of the scheme, according to the Democratic National Committee, was to “bolster Trump and denigrate the Democratic Party nominee,” Hillary Clinton, while boosting the candidacy of Trump, “whose policies would benefit the Kremlin.”

Tom Perez, chairman of the Democratic National Committee, said the party’s suit “is not partisan, it’s patriotic.”

“If the occupant of the Oval Office won’t protect our democracy, Democrats will. It is our obligation to the American people,” Perez said.

He called the alleged conspiracy “an act of unprecedented treachery: the campaign of a nominee for President of the United States in league with a hostile foreign power to bolster its own chance to win the presidency.”

The DNC in 1972 had sued President Richard Nixon’s election committee in connection with the break-in at the party’s headquarters in the Watergate building in Washington by burglars connected to the committee. The Nixon campaign settled that suit for $750,000 on the same day that Nixon resigned in disgrace in August 1974 as a result of his efforts to cover-up White House ties to the Watergate burglars.

The White House and the Trump campaign had no immediate comment on the new DNC lawsuit.

The named defendants in the lawsuit include Trump’s son Donald Trump Jr., his son-in-law Jared Kushner, former campaign chief Paul Manafort and campaign official Richard Gates, and Trump ally Roger Stone.

Also named is the Russian Federation, the general staff of the Russian armed forces, a Russian intelligence services hacker known as Guccifer 2.0., Wikileaks and its leader Julian Assange, and 10 unidentified people.

The suit says Russia is not entitled to sovereign immunity from the action, because the claims stem from Russia’s “trespass on to the DNC’s private [computer] servers” to steal information.

The DNC said that while it would be impossible “to fully repair the harm caused by the defendants, the DNC has filed this civil complaint … to hold the defendants accountable for their misconduct and to ensure transparency.”

The suit says that the Trump campaign solicited Russia’s illegal assistance and maintained secret communications with people linked to the Russian government, including a spy agency tasked with attacking the DNC.

The suit goes on to say that Russian agents trespassed into the DNC’s computer network and other electronic accounts, “collected trade secrets and other private data” and then sent that information to Wikileaks, a private group well-known for publishing secret documents.

The founder of Wikileaks, Assange, “shared the defendants’ common goal of damaging the Democratic party in advance of the election,” according to the suit.

Russia, using Wikileaks, would disseminate information stolen from the Democrats “at times when it would best suit the Trump campaign,” the suit said.

The lawsuit noted that as the stolen DNC information was released publicly, “Trump openly praised the illegal disseminations and encouraged Russia to continue violations of U.S. law through its ongoing hacking campaign.”

Perez, the DNC chairman, in a prepared statement, said, the Russian government notified the Trump campaign in advance that it had stolen Democratic emails and other information about plans by the party that Russia sought to support Trump’s candidacy.

“Rather than reporting Russia’s offer to meddle in a U.S. election, the Trump campaign welcomed Russia’s help,” Perez said. “Trump’s closest political adviser, Roger Stone, also appeared to have advance knowledge of specific plans by WikiLeaks to disseminate some of this information.”

The suit’s claims open with the words: “No one is above the law.”

“In the run-up to the 2016 election, Russia mounted a brazen attack on American Democracy. The opening salvo was an attack on the DNC, carried out on American soil.”

“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,” the suit says.

“Russia then used this stolen information to advance its own interests: destabilizing the U.S. political environment, denigrating Democratic presidential nominee, and supporting the campaign of Donald J. Trump … whose policies would benefit the Kremlin,” the suit charges.

The suit alleges conspiracy, computer fraud and abuse, misappropriation of trade secrets, trespass and other violations of the law.
