With news of business deals, undisclosed phone calls, and secret meetings coming to light daily, keeping up with the investigation into Russia's interference in the 2016 election has been difficult.

The Senate and House Intelligence Committees are conducting investigations (the latter of which has been called into question), and the FBI is in conducting its own probe to determine whethe Trump's team had any contact with Russian officials during the election, and whether the two sides coordinated to undermine Hillary Clinton's candidacy.

Here are the key names to follow in the Trump-Russia investigations:

Michael Flynn, Trump's former national security adviser

After some early criticism over his speech at a 2015 gala honoring state-sponsored news agency Russia Today in Moscow, former national security adviser Michael Flynn came under scrutiny after then-Attorney General Sally Yates warned the White House that he had "misled senior administration officials about the nature of his communications with the Russian ambassador to the United States" in January.

Flynn resigned from his role as Trump's national security adviser on February 13, after reports emerged that he had discussed the possibility of easing US-Russia sanctions with Russian ambassador Sergey Kislyak.

Paul Manafort, Trump's former campaign chairman

Paul Manafort stepped down from his role as Trump's campaign chairman in August after negative reports surfaced about his work with the ousted, pro-Russia president of Ukraine Viktor Yanukovych.

The AP reported last week that Manafort collaborated with Russian oligarch Oleg Deripaska for years to promote the interests of the Putin government and stifle anti-Russian opposition across numerous post-Soviet countries.

Manafort has volunteered to be interviewed by the House Intelligence Committee about Russia's intererence in the election.

Trump's son-in-law and top adviser, Jared Kushner, this week became the closest person to Trump to be caught up in the investigations into possible collusion between Trump associates and Russia.

Kushner has volunteered to be interviewed by the Senate Intelligence Committee about his December meetings with Russian ambassador Sergey Kislyak and, later, with the CEO of Russia's state-owned Vnesheconombank.
