Special counsel Robert Mueller and multiple congressional committees are looking into allegations that there was collusion between Russian operatives and Trump associates during the presidential campaign and transition.
Who's investigating election interference:FBI - In July of 2016, the FBI launched a counterintelligence investigation into possible links between the Russian government and Trump campaign officials.
The Senate Select Committee on Intelligence - On January 13, 2017, the committee announced that it was conducting a probe of Russian meddling. The investigation was sparked by a declassified report from the Director of National Intelligence (DNI) that described a multifaceted effort led by Russian President Vladimir Putin to interfere with the election by releasing damaging information about Clinton to help Trump. The committee is led by Richard Burr (R-NC) and Mark Warner (D-VA).
The House Permanent Select Committee on Intelligence - On January 25, 2017, the committee announced that it is investigating Russia's active measures during the presidential campaign as well as the underlying intelligence that led to the DNI's conclusions about Russia's intentions. The committee is led by Devin Nunes (R-CA) and Adam Schiff (D-CA). ((Nunes stepped away from the probe temporarily after the Ethics Committee announced it was looking into allegations he made unauthorized disclosures of classified information. When Nunes stepped away, Mike Conaway (R-TX) took his place. Even though Nunes said that he was formally stepping away from his role leading the investigation, he continues to review classified intelligence on Russia matters and he still has sway issuing subpoenas.)
The Senate Judiciary Subcommittee on Crime and Terrorism - On February 2, 2017, the subcommittee announced that it was conducting an inquiry into Russia's efforts to influence elections in the US and abroad. The subcommittee is led by Lindsey Graham (R-SC) and Sheldon Whitehouse (D-RI).
The House Committee on Oversight and Government Reform - On February 16, 2017, the committee requested information about former National Security Adviser Mike Flynn's paid speaking engagements overseas. The committee was questioning whether Flynn violated the emoluments clause of the Constitution, which bars government officials from accepting gifts from foreign governments without Congressional approval. After Trump fired FBI Director James Comey in May, the committee began looking into the circumstances surrounding the dismissal. The committee is led by Trey Gowdy (R-SC) and Elijah Cummings (D-MD).
The Senate Judiciary Committee - On May 17, 2017, the committee called on the White House and the FBI to turn over all memos related the president's interactions with Comey. In addition to conducting an oversight investigation of Comey's dismissal, the committee has held hearings on the Foreign Agents Registration Act and attempts to influence the election. The committee has also interviewed Trump's son, Donald Trump Jr. and other witnesses behind closed doors.
Special Counsel - On May 17, 2017, Deputy Attorney General Rod Rosenstein appointed former FBI Director Robert Mueller as special counsel to lead an investigation into Russian interference and related matters that could result in criminal prosecutions.

He explains that Russia and its government want to support Trump by providing opposition research on Clinton. Trump Jr. indicates he is interested in seeing the information and suggests arranging a call.
June 7-8, 2016 - Goldstone sends Trump Jr. another email about setting up an in-person meeting with a "Russian government attorney" who will be flying from Moscow to New York on June 9, to talk to representatives from the Trump campaign at Trump Tower in New York.

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.

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. 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.

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.

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 10, 2017 - CNN reports that intelligence officials briefed Trump on a dossier that contains allegations about his campaign's ties to Russia as well as salacious rumors about him.

February 9, 2017 - The Washington Post reports that Trump's national security adviser, Michael Flynn, discussed sanctions with Kislyak during the presidential transition.

June 14, 2017 - The Washington Post reports that Mueller is investigating Trump for obstruction of justice. In response to the report, Trump tweets, "They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice on the phony story. Nice."

The meeting first came to light when Kushner filed a revised version of his security clearance application in June 2017. He omitted the meeting on previous versions of the form. When news of the meeting first breaks, Trump Jr. issues a statement explaining that the primary topic of discussion was resuming an adoption program for Russian children. Trump Jr. also says that he did not know the name of the individual he was slated to meet. Further New York Times reporting reveals, however, a chain of emails in which Trump Jr. is promised damaging information about Clinton from Russian government sources, a revelation that contradicts his initial statement. Minutes before the New York Times publishes its story about the misleading statement, Trump Jr. tweets images of the email exchange obtained by the newspaper. The tweets are coupled with a statement in which Trump Jr. says the meeting was short and uneventful, as Veselnitskaya failed to deliver opposition research as promised.
July 21, 2017 - The Washington Post reports that Sessions discussed campaign matters with Kislyak during their meetings, contrary to the attorney general's testimony that the encounters were not related to the presidential race.

According to the New York Times, revisions were made after McGahn suggested a number of cuts, expressing concern about references to private meetings between Trump and Comey.

The DNI has identified the company as a Kremlin-connected organization that employs professional trolls who spread political propaganda on behalf of the Russian government. Approximately $100,000 in advertising was purchased by individuals and groups connected to about 470 inauthentic accounts. The divisive political posts included comments on gun rights, immigration, race issues and LGBT matters, according to Facebook. About one quarter of the ads were targeted specifically to run in certain areas of the country.
