Trump's business interests in Russia predate his run for office, and offer a good starting point to gain further insight into the veracity of claims regarding his proximity to the powers that be in Moscow.

President Donald Trump's decision to fire FBI director James Comey, who was in charge of investigating allegations of Russian interference in the presidential elections, raised questions on whether the leaks tarnishing the Clinton campaign actually tipped the scales in favour of the Republican candidate.

It also brought into focus the interaction between Trump's associates and Russian operatives, who had waged a sustained campaign which leaked a tranche of emails purportedly sent by Clinton during her stint in the Obama administration.

Former FBI Director Robert Mueller has been appointed special prosecutor to look into the allegations of Russian meddling and possible collusion between Trump's campaign and the Kremlin.

Trump's business interests in Russia is a good starting point to understanding the veracity of claims regarding his proximity to the powers that be in Moscow.

Here is a timeline of events that led to Comey testifying before the Senate Intelligence Committee, and how it could shape the future of the nascent Trump administration.

October 17, 2013: Trump claimed in an interview with David Letterman that he has conducted “a lot of business with the Russians.”

“Well I’ve done a lot of business with the Russians,” Trump says. “They’re smart and they’re tough.” Trump goes on to say that Putin is a “tough guy” and that he’s met him “once.”

October 14, 2015: Trump appears to cast aspersions on the intelligence community’s assessment that Russian-backed separatists were behind the downing of civilian airliner, Malaysia Airlines Flight 17. This was contrary to the US government's version, which blamed Russia for the incident.

December 10, 2015: Michael Flynn attends Russia Today’s (RT) 10th anniversary dinner. He participates in a paid speaking engagement and sits just two seats away from Putin. RT is Russia's state-run news agency, and has often been accused of carrying propaganda.

Flynn had set up a defence consultancy firm post-retirement from the U.S. army, and had even registered himself as a foreign agent with the Justice Department for $530,000 worth of lobbying work before election day. Subsequently, he was Trump's pick for the post of National Security Advisor.

December 17, 2015: Russian President Vladimir Putin praises Trump, then the front-runner in the Republican primary, at his year-end news conference.

“He is a very flamboyant man, very talented, no doubt about that. But it’s not our business to judge his merits, it’s up to the voters of the United States," Putin says. "He is an absolute leader of the presidential race, as we see it today. He says that he wants to move to another level relations, a deeper level of relations with Russia … How can we not welcome that? Of course, we welcome it.”

Trump responds in turn with praise of his own.

March 19, 2016: John Podesta’s staff is told, incorrectly, by another Clinton campaign staffer that an email instructing him to change his password is legitimate. The action allows Russian hackers into Podesta’s account.

January 15, 2017: On CBS News, Vice President-elect Mike Pence is asked if “ Flynn was in touch with the Russian ambassador on the day the United States government announced sanctions for Russian interference with the election.
