These GRU officers, in their official capacities, engaged in a sustained effort to hack into the computer networks of the Democratic Congressional Campaign Committee, the Democratic National Committee, and the presidential campaign of Hillary Clinton, and released that information on the internet under the names "DCLeaks" and "Guccifer 2.0" and through another entity.
Computer records related to at least 500,000 voters were stolen, but no evidence has emerged that the election itself was compromised or that the result was affected.
One group of officers were tasked with infiltrating computers and stealing data, while another worked to distribute it through anonymous channels in the U.S.
The indictment - announced days before US President Donald Trump's summit with Russian President Vladimir Putin - stands as the clearest Justice Department allegation yet of Russian efforts to interfere, through illegal hacking, in the election before Americans went to the polls.
Starting in June 2016, they released tens of thousands of these documents using online pseudonyms, such as "Guccifer 2.0" and "DC Leaks". But he noted the indictment does not allege those two Americans knew they were communicating with Russians, nor does it state any USA citizen committed a crime.
They corresponded with Americans but there's no information the Americans knew who they were talking to, said Rosenstein.
"This has to be the first time that a major presidential candidate has actively encouraged a foreign power to conduct espionage against his political opponent", it said.
While President Donald Trump hasn't been a supporter of this probe previously calling it a witch hunt, Rosenstein said that he has been briefed about this indictment earlier this week and "is fully aware of today's actions by the department".
Mueller and a team of prosecutors have been working since May 2017 to determine if any Trump associates conspired with Russian Federation to interfere in the election.
After the indictments were announced, top Senate Democrat Chuck Schumer called on Trump to cancel his meeting with Putin until Russian Federation takes steps to prove it won't interfere in future elections.
"Russia, if you're listening", Trump said, "I hope you're able to find the 30,000 emails that are missing".
A review of the indictment found that on line 22, the special counsel investigation said that Russian intelligence officers spent the better part of 2016 attempting to hack into email accounts associated with the Clinton Campaign.
We want to hear from you. He stressed that Mueller's investigation is ongoing. Among those indictments includes three Trump associates who have pleaded guilty and 14 other Russian citizens.
A statement from the White House did not address the allegations of Russian government interference and focused only on what was not in the indictment. "But I love getting along with Russian Federation and China and other countries".
