The Russia imbroglio is barreling into another year that could deliver even more revelations and political heat than the last one — and maybe even a big finale.

The criminal cases of several key players are unresolved, new charges could be ripe, and House Democrats are set to sweep into Washington with huge ambitions about how to use their investigative and oversight powers now that they wield the majority.

Defense Secretary Jim Mattis, a living Marine Corps legend who made history by securing special permission from Congress to lead the Pentagon, is stepping down after a slow freeze-out by President Trump.

A federal judge delayed sentencing former national security adviser Michael Flynn on Tuesday after he pleaded guilty to lying to investigators about his talks with Russia's ambassador.

U.S. District Judge Emmet Sullivan said he has significant outstanding questions about the case, including how the government's Russia investigation was impeded and the material impact of Flynn's lies on the special counsel's inquiry.

Each new dawn seems to bring a major new headline in the Russia investigation, including a number of important courtroom developments this month.

Here's what you need to know about what has happened so far this week in this often complex and fast-moving saga.

Michael Cohen is going to prison, but he says he isn't finished yet

Updated at 4:13 p.m. ET

A federal judge sentenced Donald Trump's former lawyer Michael Cohen to three years in prison on Wednesday following Cohen's guilty pleas to a number of political and finance crimes.

Those three years would be followed by three years of supervised release, and Cohen also is subject to forfeiture of $500,000, restitution of $1.4 million and fines totaling $100,000.

Cohen had asked for leniency. He said in court, however, that he accepts responsibility for his actions.

Last week in the Russia investigations: The special counsel ties up loose ends, but that may not mean the finish line is any closer.

Endings and beginnings

Never mind that it still isn't fully clear what the Russia imbroglio is — what picture all the puzzle pieces are supposed to form when they're put together.

An even more basic question that's just as difficult to answer is: How much longer will it go?

Two of Donald Trump's former top aides are looking at years in federal prison — and Trump and his camp allegedly are connected to many of the crimes in which they've been charged.

Those were among the big takeaways from the release of court documents on Friday evening in a pair of cases that have ensnared Trump's former longtime personal lawyer and the veteran political pro who ran his presidential campaign for a time in 2016.

Editor's note: An earlier version of this report mischaracterized an answer Donald Trump Jr. gave to Senate investigators in 2017 about the prospective projects his family was negotiating with people in Moscow.

There have been so many big developments this week in the Russia story that it's tough to keep them all straight.

Here's what you need to know.

Cohen admits lying to Congress

What happened? Donald Trump's former longtime lawyer Michael Cohen admitted on Thursday that he and others working for Trump negotiated with important Russians over a possible Trump Tower in Moscow well into the presidential campaign in 2016.

Updated at 3:03 p.m. ET

A pardon for ex-campaign chairman Paul Manafort is not "off the table," President Trump said Wednesday, following a report that Manafort's lawyer has briefed Trump's lawyers about his testimony in the Russia investigation.

Trump told the New York Post that he hasn't talked about clemency for Manafort but that the door remains open.

A spate of new reports on Tuesday brought new suggestions about ties between Americans in Donald Trump's campaign and the Russians who attacked the 2016 election — but nothing official from the government and only public denials from many of those involved.

The White House declined to address a report on Tuesday that said Paul Manafort, Trump's onetime campaign chairman, met in person with WikiLeaks founder Julian Assange.

Critics intensified their pressure on the acting attorney general on Tuesday, but the Justice Department — including the office of special counsel Robert Mueller — says it's carrying out business as usual.

Senate Minority Leader Chuck Schumer asked the Justice Department's watchdog to investigate whether there have been any "unlawful or improper communications" between the White House and acting Attorney General Matthew Whitaker.

This week in the Russia investigations: President Trump says he, and not his lawyers, completed written questions for the special counsel. Now, the ball is back in Robert Mueller's court.

Paper jam

President Trump says he has finished his open-book, take-home exam.

Updated at 2:13 p.m. ET

President Trump has completed written answers to questions about the Russia investigation from Justice Department special counsel Robert Mueller.

The president told reporters on Friday that he wrote the answers, not his lawyers, and that he did so "very easily."

Trump said he suspected some of the questions were designed to be pitfalls and catch him in a "perjury trap" — to induce him to lie about things for which prosecutors might already have contradictory evidence.
