The latest political sandstorm in the Russia saga is over four pages of paper that have never seen the light of day. Here's what you need to know to make sense of what's going on with this story.

1. What exactly is this memo that everyone is talking about?

Updated at 3:39 p.m. EST on Jan. 24

The hottest thing on Capitol Hill this week is a document that no one in the outside world is allowed to see.

A secret four-page memorandum prepared by the chairman of the House Intelligence Committee has become a rallying cry for Republicans waging a sustained campaign against the FBI and the Justice Department.

The document, pulled together by Rep. Devin Nunes, R-Calif., alleges that the Obama administration abused the Foreign Intelligence Surveillance Act in targeting the Trump campaign.

The former British intelligence officer who authored the infamous Russia dossier wanted to show it to the FBI because he was concerned that then-presidential candidate Donald Trump was being "blackmailed."

Members of Congress have not made life easy for the leaders of the Justice Department this month, and FBI Deputy Director Andrew McCabe was next in line on Tuesday.

McCabe testified behind closed doors before the House Intelligence Committee as part of its investigation into Russian interference in the 2016 election.

His appearance follows attacks by President Trump and Republican allies on him specifically, the FBI, the Justice Department and special counsel Robert Mueller, including accusations of political bias.

During the 2016 presidential campaign, Donald Trump Jr. was in direct contact with WikiLeaks at the same time the muckraking website was publishing hacked emails from Democratic officials that proved damaging to the Clinton campaign, according to several major publications.

Following the reports, Trump Jr. acknowledged the contact in a tweet detailing one exchange with the radical transparency organization.

According to President Trump, some Republicans in Congress and conservative media outlets, the Russia scandal is heating up.

No, not that one.

It's an alternative Russia scandal. And the claims go like this:

As secretary of state, Hillary Clinton approved the 2010 sale of a mining company to Russia. This gave the Russians control of 20 percent of U.S. uranium and placed U.S. national security at risk. In return, the Clinton Foundation received $145 million in pledges and donations.

Updated at 11:56 p.m. ET: NPR has obtained the full memo from a Democratic source. Read it at the bottom of this story.

What, exactly, did the Democratic National Committee and Hillary Clinton's presidential campaign agree to in 2015, before any votes had been cast in the Democratic primary?

Updated at 5:10 a.m. ET

Hillary Clinton's campaign gained significant control over the Democratic National Committee's finances and strategy more than a year before the election in exchange for helping the party retire lingering debt from the 2012 presidential campaign, according to a new book by a former party chairwoman.
