Russia carried out a campaign to influence the outcome of the 2016 American presidential election, denigrating Hillary Clinton and boosting Donald J. Trump, according to American intelligence agencies. President Vladimir V. Putin of Russia personally ordered it.
The F.B.I., citing four Trump campaign aides’ ties to Russia, opened a counterintelligence investigation in the summer of 2016 to determine whether Trump associates aided Russia’s election interference.
Robert S. Mueller III, the former F.B.I. director, was appointed the special counsel in May 2017 to take over the investigation. The inquiry has expanded to examine whether President Trump tried to obstruct the investigation itself.
Nineteen people — including four Trump associates — and three companies have been indicted in the case. Five have pleaded guilty; 13 are Russians accused of meddling in the election.
THE MAJOR FOCUSES OF THE INVESTIGATION
Mr. Mueller is investigating Russia’s efforts to influence the presidential race and sow discord by spreading inflammatory messages on social media and stealing emails from Mrs. Clinton’s campaign chairman and the Democratic National Committee, which were then strategically released to undermine the Clinton campaign.
Investigators are examining what Mr. Trump’s aides and associates knew about Russia’s meddling, particularly the release of thousands of stolen Democratic emails stolen, and whether any of them aided Moscow’s effort.
Mr. Mueller is investigating an array of the president’s actions — including the firing of the former F.B.I. director, James B. Comey — to determine whether Mr. Trump sought to impede the investigation into Russia’s actions.
Mr. Mueller is investigating whether Trump associates ran afoul of American lobbying or anti-corruption laws. Two aides to the Trump campaign, including its onetime chairman, were charged with financial crimes related to their work as advisers to a pro-Russia former president of Ukraine.
