On Tuesday, Bloomberg published a blockbuster report showing Russian hackers attempted to breach United States elections databases and systems in 39 states leading up to the contentious 2016 presidential election.

Coupled with reporting from the Intercept and several other news outlets, the report paints a picture of Russian meddling that was much more widespread than was previously known. It also shows that the Obama administration, seeking to court Russian cooperation in Syria, did not publicly confront Russia over the hacking, even after U.S. intelligence agencies had established that Russia was attempting to sway the 2016 presidential election.

Based on what we know now, here's a timeline of Russian involvement in the election:

Summer 2015

A group of hackers identified by security researchers and the U.S. government as "Cozy Bear," also known as "CozyDuke" and "Advanced Persistent Threat 29," successfully "spear-phished" the Democratic National Committee, according to security researchers brought on later to investigate the hack. Cozy Bear is widely believed to be a Russian government-run operation and is believed by some to be linked to Russia's main intelligence service, the FSB, a successor to the KGB, Russian President Vladimir Putin's former outfit.

September 2015

FBI Special Agent Adrian Hawkins contacted the DNC and informed them of the hack, the New York Times later reported. But Yared Tamene, the DNC contractor who took Hawkins' call, wasn't sure Hawkins actually worked for the FBI. "I had no way of differentiating the call I just received from a prank call," he wrote in a memo obtained by the Times. Through the end of September and into October, Hawkins continued to attempt to inform the DNC it had been hacked.

March 2016

The DNC concluded Hawkins was, in fact, an FBI agent, according to the Times.

March 22 , 2016

Hillary Clinton campaign chairman John Podesta fell victim to a spear-phishing email by "Fancy Bear," a separate hacking group that, like Cozy Bear, is believed to be backed by the Russian government. Fancy Bear is believed by some security researchers to be connected to Russia's military intelligence outfit, the GRU. Clinton campaign aide Charles Delavan urged Podesta to click a link in the spear-phishing email, which he said was "legitimate," to reset his password. Delavan later said he meant to write that the email was illegitimate. Podesta did so, giving Fancy Bear access to his email account.

Around March or April, 2016

Hackers gained access to the DNC's and the Democratic Congressional Campaign Committee's main networks, the Times later reported.

April 2016

The DNC installed a "robust set of monitoring tools" to safeguard its network.

April 29 2016

Tamene, the DNC contractor, told DNC CEO Amy Dacey that "an unauthorized person, with administrator-level security status, had gained access to the DNC's computers," according to a memo obtained by the Times. The DNC hired cyber security firm CrowdStrike to investigate the hack. Within days, CrowdStrike tells the DNC the hack likely originated in Russia.

The Washington Post first reported the hack.

A person or persons claiming to be a hacker called Guccifer 2.0 claimed responsibility for the hack and said they would release documents hacked from the DNC to WikiLeaks. Guccifer 2.0 claimed to be a lone hacker.

Early July, 2016

A contractor working for the Illinois state board of elections detected a hack into the state's voter registration records, setting off a nationwide federal investigation that found hackers had infiltrated elections systems in 39 states, Bloomberg reported.
