Top U.S. intelligence officials have briefed leaders in Washington about an explosive — but unverified — document that alleges collusion between Russia and President-elect Donald Trump, NPR has learned.

The brief, which NPR has seen but not independently verified, was given by Senate Armed Services Committee Chairman John McCain to FBI Director James Comey on Dec. 9. Details from it have been part of presentations by Comey and other intelligence leaders to Trump, President Obama and key leaders in Congress.

The week before Donald Trump takes the oath of office will set the stage for his entry into the Oval Office. Not only will at least nine of his Cabinet nominees begin their Senate confirmation hearings, but the president-elect himself will face reporters at a long-awaited press conference, where he may address how he plans to separate his business interests from his presidency.

On top of that, President Obama steps into the spotlight one last time, on Tuesday evening in Chicago, for a farewell address in which he's likely to frame his legacy.

President-elect Donald Trump is rounding out his White House team — installing several trusted campaign advisers to senior West Wing positions.

Kellyanne Conway will serve as counselor to the president, the transition team announced on Thursday. Sean Spicer will be press secretary, and Jason Miller has been named director of communications.

President-elect Donald Trump, in a statement early this morning, announced his intention to nominate ExxonMobil chairman and CEO Rex Tillerson to lead the State Department and become the country's top diplomat.

The selection, which had been rumored for the past week, is unusual in a number of ways, and could face more scrutiny than usual when the Senate holds confirmation hearings.

Here are some key facts about the president-elect's nominee for the final major position to be filled in his Cabinet:

On Sunday, President-elect Donald Trump told Fox News that he wouldn't feel "bound by a 'One China' policy unless we make a deal with China having to do with other things, including trade."

The One China policy has guided U.S.-China discourse since 1979, when Washington established diplomatic relations with Beijing and downgraded its embassy in Taiwan.

A $25 million settlement agreement has been reached in the civil fraud lawsuits against President-elect Donald Trump and Trump University, according to New York's state attorney general.

Reince Priebus once joked about his job as chairman of the Republican National Committee that people assumed he must be miserable. But Priebus said he didn't see it that way. "I'm not pouring Bailey's in my cereal," he told CNN.

Now, as newly named chief of staff to President-elect Donald Trump, Priebus has his work cut out for him.

Priebus will have a large say in hiring West Wing staff, and will "be in charge of day to day operations," he told Fox News on Monday morning. He'll also have the president-elect's ear as a top adviser.

Less than a week after his election, Donald Trump has begun to fill out the team he plans to bring with him to the White House. The president-elect announced Sunday that he has selected Republican National Committee Chairman Reince Priebus to serve as chief of staff in his incoming administration.

In the same announcement, Priebus' appointment shared top billing with the news that Trump campaign CEO Stephen K. Bannon will serve as chief strategist and senior counselor to the president.

He'll build a border wall and he'll deport millions of people who are in the U.S. illegally, President-elect Donald Trump says, promising to keep his campaign pledges on immigration in his first prolonged interview since winning the White House.
