Here's a look at hacking incidents during the 2016 presidential campaign and Russian meddling in the election. For details about investigations into hacking and efforts to interfere with the election, see 2016 Presidential Election Investigation Fast Facts.
Timeline:
September 2015 - The FBI contacts the Democratic National Committee's help desk, cautioning the IT department that at least one computer has been compromised by Russian hackers. A technician scans the system and does not find anything suspicious.
WHY DIDN'T THE FBI NOTIFY TRUMP THAT THEY SUSPECTED RUSSIAN HACKING??
November 2015 - The FBI reaches out to the DNC again, warning them that one of their computers is transmitting information back to Russia. DNC management later says that IT technicians failed to pass along the message that the system had been breached.
March 19, 2016 - Clinton campaign chairman John Podesta receives a phishing email masked as an alert from Google that another user had tried to access his account. It contains a link to a page where Podesta can change his password. He shares the email with a staffer from the campaign's help desk. The staffer replies with a typo - instead of typing "This is an illegitimate email," the staffer types "This is a legitimate email." Podesta follows the instructions and types a new password, allowing hackers to access his emails.
June 12, 2016 - During an interview on British television, WikiLeaks founder Julian Assange says that the website has obtained and will publish a batch of Clinton emails.
OBAMA, CIA AND FBI KNEW RUSSIANS WERE HACKING - WHAT DID THEY DO TO STOP IT?? ANOTHER FAILURE?
June 14, 2016 - The Washington Post reports hackers working for the Russian government accessed the DNC's computer system, stealing oppositional research on Donald Trump and viewing staffers' emails and chat exchanges.
The Kremlin, however, denies that the government was linked to the hack, and a US official tells CNN that investigators have not yet concluded that the cyberattack was directed by the Russian government.
June 15, 2016 - A cybersecurity firm hired by the DNC posts a public notice on its website describing an attack on the political committee's computer network by two groups associated with Russian intelligence. According to the post, two Russian-backed groups called "Cozy Bear" and "Fancy Bear" tunneled into the committee's computer system. In response, a blogger called Guccifer 2.0 claims that he alone conducted the hack, not the Russians. As proof, he posts internal DNC memos and opposition research on Trump. Furthermore, Guccifer 2.0 claims to have passed along thousands of files to WikiLeaks. Trump offers his own theory on the origins of the attack: suggesting in a statement that the DNC hacked itself to distract from Clinton's email scandal.
July 22, 2016 - Days before the Democratic National Convention, WikiLeaks publishes nearly 20,000 emails hacked from the DNC server. The documents include notes in which DNC chair Debbie Wasserman Schultz insults staffers from the Bernie Sanders campaign and messages that suggest the organization was favoring Clinton rather than remaining neutral. Wasserman Schultz resigns in the aftermath of the leak.
July 25, 2016 - The FBI announces it has launched an investigation into the DNC hack. Although the statement doesn't indicate that the agency has a particular suspect or suspects in mind, US officials tell CNN they think the cyberattack is linked to Russia.
July 27, 2016 - During a press conference, Trump talks about Clinton's use of a private email server while she was secretary of state and calls on hackers to find deleted emails. "Russia, if you're listening, I hope you're able to find the 30,000 emails that are missing," says Trump. Newt Gingrich, a Trump surrogate, defends Trump in a Tweet, dismissing the comment as a "joke."
August 12, 2016 - Hackers publish cell phone numbers and personal email addresses for Nancy Pelosi and other members of the Democratic Congressional Campaign Committee.
September 1, 2016 - During an interview with Bloomberg News, President Vladimir Putin says that he and the Russian government have no ties to the hackers. He says that the identity of the culprit or culprits is not as important as the content of the leaks, and ultimately the hackers revealed important information for voters.
September 22, 2016 - Democrats Dianne Feinstein and Adam Schiff, ranking members of the Senate and House Intelligence Committees, issue a joint statement declaring that based on information they received during congressional briefings, they believe that Russian intelligence agencies are carrying out a plan to interfere with the election. They call on Putin to order a halt to the activities.
September 26, 2016 - During a presidential debate with Clinton, Trump questions whether the DNC cyberattack was carried out by a state-sponsored group or a lone hacker. "It could be Russia, but it could also be China. It could also be lots of other people. It also could be somebody sitting on their bed that weighs 400 pounds."

November 29, 2016 - A group of Democratic senators sends a letter to President Barack Obama calling on intelligence agencies to declassify information about "the Russian Government and the US election." Sources later tell CNN that new intelligence has been shared with lawmakers suggesting that Russia's purpose for meddling in the election was to sway voters towards Trump, rather than broadly undermining confidence in the system.
December 9, 2016 - The Washington Post reports the CIA has determined that Russian hacking was conducted to boost Trump and hurt Clinton during the presidential campaign. The Trump transition team dismisses the CIA's findings. President Obama asks intelligence agencies to review the hacking incidents in 2016 and other cyberattacks on political campaigns dating back to 2008. The agencies are asked to deliver their findings before Obama leaves office on January 20. A Russian foreign ministry spokesman expresses skepticism about the review and asks US investigators to share their evidence of government-sponsored cyber espionage. Meanwhile, media critics question the Post's reliance on anonymous sources for the CIA report and advise readers to be wary of claims in the article due to the lack of publicly available evidence to support the spy agency's conclusions.

Putin ordered a multifaceted influence campaign that included spreading pro-Trump propaganda online and hacking the DNC and Podesta. Bracing for a possible Clinton win, Russian bloggers were prepared to promote a hashtag #DemocracyRIP on election night. Paid social media users, aka "trolls," shared stories about Clinton controversies to create a cloud of scandal around her campaign.
January 6-7, 2017 - Trump issues a statement after his meeting with intelligence officials. In the statement, he acknowledges that the Russian government may have been linked to the DNC hacking but declares that cyberattacks did not impact the outcome of the election because voting machines were not breached.
In a series of tweets, he repeats that hacking did not affect election results and says that he wants to improve relations with Russia.
March 10, 2017 - In an interview with the Washington Times, Trump ally Roger Stone says that he had limited interactions via Twitter with Guccifer 2.0 during the campaign.
