The House's impeachment inquiry has been driven forward by new disclosures of what exactly President Trump wanted the government of Ukraine to do — revealed in 3 key documents, but nonetheless distorted and disputed along the way.

We've gathered the key players, events and disclosures of the Trump-Ukraine saga in one place to clear up what's happened so far and examine where we go from here.

The key players

The key dates

2014

Russia intervenes militarily in Ukraine and annexes Crimea.

Hunter Biden joins the board of a Ukrainian energy company, Burisma, raising conflict-of-interest concerns because the company faces corruption claims and his father is the Obama administration’s point man on Ukraine.

Fact check: Joe Biden did push for a Ukrainian prosecutor to be fired — but not to protect his son (read our full fact check).

2016

Ukraine's National Anticorruption Bureau releases damaging information about Paul Manafort, Trump's then-campaign chairman who was a former adviser to Ukraine's Kremlin-backed president, Viktor Yanukovych.

Manafort resigns and is later indicted for failing to register as a foreign agent. Trump becomes "obsessed" with Ukraine's role in embarrassing his campaign, per the NYT.

"Mixed in with the issues related to Mr. Manafort is the unsubstantiated theory that the hack of Democratic National Committee emails in 2016 could have been carried out by Ukrainians who in turn pinned the blame on Russia."

2019

The key documents

1. The whistleblower complaint

"In the course of my official duties, I have received information from multiple U.S. Government officials that the President of the United States is using the power of his office to solicit interference from a foreign country in the 2020 U.S. election. This interference includes, among other things, pressuring a foreign country to investigate one of the President's main domestic political rivals. The President's personal lawyer, Mr. Rudolph Giuliani, is a central figure in this effort. Attorney General Barr appears to be involved as well."

So begins a 9-page document — much, but not all of which has subsequently been substantiated. Read it.

The whistleblower alleges White House officials restricted access to records of the July call for political reasons — and had taken similar extreme measures with previous calls.

He describes efforts by Giuliani to secure Ukrainian cooperation in investigating the Bidens, and by Volker and Sondland to help the Ukrainians "navigate" Trump's demands.

He draws a line between Trump's suspension of military aid and pressure on Zelensky to "play ball" with the investigations.

2. The Trump-Zelensky call memo:

"[W]e are almost ready to buy more Javelins [missiles] from the United States for defense purposes."

— Zelensky

"I would like you to do us a favor though because our country has been through a lot and Ukraine knows a lot about it."

— Trump

That's the most hotly debated portion of a 5-page partial transcript of the July call. Read the memo.

Trump's accusers claim that in that exchange, he's directly linking the delivery of sorely needed military aid with politically motivated investigations.

Trump has repeatedly described the call as "perfect."

3. The text messages:

"As I said on the phone, I think it’s crazy to withhold security assistance for help with a political campaign."

— Bill Taylor, on Sept. 9

"Bill, I believe you are incorrect about President Trump’s intentions. The President has been crystal clear no quid pro quo’s of any kind. The President is trying to evaluate whether Ukraine is truly going to adopt the transparency and reforms that President Zelensky promised during his campaign I suggest we stop the back and forth by text."

— Gordon Sondland, in response

The text messages released by Volker show him and Sondland working with Giuliani to secure Ukrainian commitments to pursue the investigations Trump wants. Read the texts.

Hours before the Trump-Zelensky call, Volker tells Yermak he's been told by the White House that Zelensky must convince Trump "he will investigate / 'get to the bottom of what happened' in 2016" — before securing a White House invitation.

Taylor, the top U.S. diplomat in Ukraine, is a recurring voice of concern.

He threatens to resign in one text and in another asks, "Are we now saying that security assistance and WH meeting are conditioned on investigations?"

The Wall Street Journal and others have reported that before denying to Taylor via text that there is a quid pro quo, Sondland phoned Trump directly.

The big picture: Everyone agrees that Trump pressed Zelensky to investigate the Bidens and matters relating to the 2016 election.

Trump and his allies paint that as part of an effort to encourage Ukraine to root out corruption. They also claim the whistleblower was politically motivated.

Democrats who consider this grounds for impeachment claim Trump betrayed America’s interests and sold out Ukraine to further his own political aims.
