A look at where the investigations related to President Donald Trump stand and what may lie ahead for him:

 

What's this about?

Trump is facing criminal investigations in Washington and New York.

Special counsel Robert Mueller is looking into whether the Trump campaign coordinated with Russia and whether the president obstructed the investigation.

Trump also plays a central role in a separate case in New York, where prosecutors have implicated him in a crime. They say Trump directed his personal lawyer Michael Cohen to make illegal hush money payments to two women as a way to quash potential sex scandals during the campaign.

 

What should I know?

The chief federal judge in Washington last week extended the grand jury hearing testimony in the special counsel's investigation.

The grand jury was impaneled in July 2017 for 18 months, and the term was scheduled to expire in the coming days. Federal court rules allow the grand jury's service to be extended up to six months if it is in the "public interest."

Separately, now that Democrats have taken over the House, some party members are making noise about trying to remove Trump from office.

California Rep. Brad Sherman and Texas Rep. Al Green introduced articles of impeachment against Trump on Thursday, the first day of the new Congress.

Also Thursday, House Judiciary Committee Democrats introduced legislation to protect Mueller from being fired. Trump has repeatedly criticized Mueller's investigation.

The legislation would allow any special counsel who is removed from office to challenge his or her removal in court and would put into law existing regulations that a special counsel may only be removed for good cause.

 

What's up with
AG nominee?

Trump's pick for attorney general, William Barr, sent an unsolicited memo to the Justice Department last year criticizing parts of the Mueller probe as "fatally misconceived."

The 20-page memo, sent in June while Barr was in private practice and months before he was selected by Trump for the Justice Department job, may prompt questions about his ability to oversee the  investigation fairly.

 

So ... was there
Russia collusion?

There is no smoking gun when it comes to the question of Russia collusion. But the evidence so far shows a broad range of Trump associates had Russia-related contacts during the 2016 presidential campaign and transition period, and that several lied about the communication.

There is also evidence that some people in the president's orbit were discussing a possible email dump from WikiLeaks before it occurred. American intelligence agencies and Mueller have said Russia was the source of hacked material released by WikiLeaks during the campaign that was damaging to Hillary Clinton's presidential effort.

 

Other questions

• What about obstruction of justice? That is another unresolved question that Mueller is pursuing. Investigators have examined key episodes such as Trump's firing of former FBI Director James Comey and his fury over the recusal from the investigation of former Attorney General Jeff Sessions.

• What does Trump say about all this? Trump has repeatedly slammed the Mueller investigation as a "witch hunt" and insisted there was "NO COLLUSION" with Russia. He also says his now-former lawyer, Cohen, lied to get a lighter sentence in New York.
