Where the investigations related to President Trump stand

Where investigations related to President Donald Trump stand and what may lie ahead for him:

WHAT'S THIS ALL ABOUT?

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. New York prosecutors also are looking into Trump's inaugural fund.

WHAT DO I NEED TO KNOW RIGHT NOW?

A sentencing memo filed Saturday is very tough on former Trump campaign chairman Paul Manafort. It says he committed crimes that cut to "the heart of the criminal justice system" and over the years deceived everyone from bookkeepers and banks to federal prosecutors and his own lawyers. The memo was filed by special counsel Robert Mueller's office.

In the memo, submitted in one of two criminal cases Manafort faces, prosecutors do not yet take a position on how much prison time he should serve or whether to stack the punishment on top of a separate sentence he will soon receive in a Virginia prosecution. But they do depict Manafort as a longtime and unrepentant criminal who committed "bold" crimes, including under the spotlight of his role as campaign chairman and later while on bail, and who does not deserve any leniency.

SO ... DID THE TRUMP CAMPAIGN COLLUDE WITH RUSSIA?

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

There is evidence that some people in Trump'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 the anti-secrecy group WikiLeaks during the campaign that was damaging to Democrat Hillary Clinton's presidential effort.

OTHER QUESTIONS TO CONSIDER:

—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 Comey and Trump's fury over Attorney General Jeff Sessions' recusal.

—WHAT DOES TRUMP HAVE TO 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 Cohen lied to get a lighter sentence in New York.

—WHEN WILL IT ALL WRAP UP? It's unclear. Acting Attorney General Matthew Whitaker said late last month that the probe is "close to being completed," the first official sign that Mueller's investigation may be wrapping up. But he gave no specific timetable.
