Friday was one of those times, as Mr. Mueller and his team indicted 12 Russian military intelligence officers for allegedly hacking into the Democratic National Committee and the Hillary Clinton campaign.
In a July 27, 2016, speech, then-candidate Donald Trump called on Russian hackers to find emails from Hillary Clinton, his Democratic opponent in the USA presidential campaign.
Second, Friday's move is typical in that Mueller's indictments tend to always seem a bit surprising in their breadth, indicating that the investigation is a little broader, a little farther along, and a little more wide-ranging than many observers think. That includes four former Trump campaign and White House aides, three of whom have pleaded guilty to different crimes and agreed to cooperate, as well as 13 Russians accused of participating in a hidden but powerful social media campaign to sway American public opinion in the 2016 election. The ministry says "obviously, the goal of this is to spoil the atmosphere" before Monday's summit between President Vladimir Putin and President Trump in Helsinki, Finland.
Using the name "Guccifer 2.0", the Russians told Trump associate Roger Stone ― identified in the indictment as "a person who was in regular contact with senior members of the presidential campaign of Donald J. Trump" ― that it would be their "great pleasure" to help.
It was the most detailed United States accusation yet that Russian Federation meddled in the election with the eventual aim of trying to boost Republican Trump's campaign.
"I love the United States", Trump continued.
Mueller's indictment appears to mention the transaction, mentioning that in August, 2016, "the conspirators, posing as Guccifer 2.0, transferred approximately 2.5 gigabytes of stolen data from the DCCC to a then-registered state lobbyist and online source of political news".
Some researchers said the indictment might have depended on US signals intelligence, the fruits of which are rarely revealed, because it quotes electronic messages sent to an unidentified organization presumed to be London-based WikiLeaks.
"Russia, if you're listening", Trump said, "I hope you're able to find the 30,000 emails that are missing". Trump complained about the Russian Federation investigation hours before the indictment, saying the "stupidity" was making it "very hard to do something with Russian Federation".
That evening, the indictment says, the Russians attempted to break into email accounts used by Clinton's personal office, along with 76 Clinton campaign email addresses.
"When we confront foreign interference in American elections, it is important for us to avoid thinking politically as Republicans or Democrats and instead to think patriotically as Americans", he said.
Trump complained about "stupidity" when asked about Mueller's probe earlier Friday, at a news conference in Britain with Prime Minister Theresa May. "But it makes it very hard to do something with Russian Federation". "If President Trump is not prepared to hold Putin accountable, the summit in Helsinki should not move forward".
