The spies started by sending spearphishing e-mails to members of Ms. Clinton's campaign and other Democratic officials, the indictment says. "I think that we would have a chance to have a very good relationship with Russian Federation". "So long as we are united in our commitment to the shared values enshrined in the Constitution, they will not succeed".
The indictment accuses the Russian hackers, starting in March 2016, of covertly monitoring the computers of dozens of Democratic officials and volunteers, implanting malicious computer code known as malware to explore the networks and steal data, and sending phishing emails to gain access to accounts.
Russia's foreign ministry described the allegations as a "heap of conspiracy schemes" meant to "damage the atmosphere" before Monday's talks.
Officials at the time said "no more than about 200,000" voters had been affected by a cyber-hacking of the registration rolls.
Trump has repeatedly said the investigation into suspected Russian interference in the 2016 USA election - which he casts as a "rigged witch hunt" - makes it hard for him to do substantive deals with Moscow.
Senator Patrick Leahy said the indictment charging 12 Russian intelligence officers with conspiring to interfere with our presidential election is no witch hunt.
News of the indictment came as Trump was meeting Queen Elizabeth II and just 72 hours before his meeting with Putin. "Democrats contend Republicans" fixation on Rosenstein is really an effort to undermine special counsel Robert Mueller, who reports to Rosenstein and has been making inroads in his investigation of the Russian election interference plot.
"There's no allegation in this indictment that any American citizen committed a crime", Rosenstein added, although the "conspirators corresponded with several Americans during the course of the conspiracy through the internet".
According to Obama aides, Obama tried to formulate a bipartisan statement on alleged Russian election interference in September 2016, two months before the election, but saw the effort "watered down" by Republican Senate majority leader Mitch McConnell.
A one-on-one meeting with Trump gives the meticulously prepared Russian President a chance to appear the more assured player, in a sit-down with his famously brash and improvisational American counterpart. Both investigations unfolded during the presidential election, causing the FBI - which prides itself on independence - to become entangled in presidential politics in ways that are continuing to shake out.
He maintained, however, that Russian Federation has no interest meddling in U.S. elections and never will.
As of Friday, the inquiry has indicted 32 people - mostly Russian nationals in absentia - as well as three companies and four former Trump advisers.
"Now this is becoming contagious, I believe, and highly likely thing and the assertion that there is no other credible explanation is becoming a rule on which the Western friends try to base their policy on Russian Federation", he said.
"President Trump should cancel his meeting with Vladimir Putin until Russian Federation takes demonstrable and transparent steps to prove that they won't interfere in future elections", Schumer said.
The charges include conspiracy to commit an offense against the US, aggravated identity theft and conspiracy to launder money.
