For two years, Americans have tried to absorb the details of the 2016 attack: spies, leaked emails, social media fraud — and President Trump’s claims that it’s all a hoax. The Times explores what we know and what it means.
On an October afternoon before the 2016 election, a huge banner was unfurled from the Manhattan Bridge in New York City: Vladimir V. Putin against a Russian-flag background, and the unlikely word “Peacemaker” below. It was a daredevil happy birthday to the Russian president, who was turning 64.
In November, shortly after Donald J. Trump eked out a victory that Moscow had worked to assist, an even bigger banner appeared, this time on the Arlington Memorial Bridge in Washington: the face of President Barack Obama and “Goodbye Murderer” in big red letters.
The police never identified who had hung the banners, but there were clues. The earliest promoters of the images on Twitter were American-sounding accounts, including @LeroyLovesUSA, later exposed as Russian fakes operated from St. Petersburg to influence American voters.
The Kremlin, it appeared, had reached onto United States soil in New York and Washington. The banners may well have been intended as visual victory laps for the most effective foreign interference in an American election in history.
For many Americans, the Trump-Russia story as it has been voluminously reported over the past two years is a confusing tangle of unfamiliar names and cyberjargon, further obscured by the shout-fest of partisan politics. What Robert S. Mueller III, the special counsel in charge of the investigation, may know or may yet discover is still uncertain. President Trump’s Twitter outbursts that it is all a “hoax” and a “witch hunt,” in the face of a mountain of evidence to the contrary, have taken a toll on public comprehension.
But to travel back to 2016 and trace the major plotlines of the Russian attack is to underscore what we now know with certainty: The Russians carried out a landmark intervention that will be examined for decades to come. Acting on the personal animus of Mr. Putin, public and private instruments of Russian power moved with daring and skill to harness the currents of American politics. Well-connected Russians worked aggressively to recruit or influence people inside the Trump campaign.
To many Americans, the intervention seemed to be a surprise attack, a stealth cyberage Pearl Harbor, carried out by an inexplicably sinister Russia. For Mr. Putin, however, it was long-overdue payback, a justified response to years of “provocations” from the United States.
And there is a plausible case that Mr. Putin succeeded in delivering the presidency to his admirer, Mr. Trump, though it cannot be proved or disproved. In an election with an extraordinarily close margin, the repeated disruption of the Clinton campaign by emails published on WikiLeaks and the anti-Clinton, pro-Trump messages shared with millions of voters by Russia could have made the difference, a possibility Mr. Trump flatly rejects.
