Trump Impeachment Inquiry: A Guide To Key People, Facts And Documents

The Democrat-led House of Representatives is leading an impeachment inquiry into President Trump. While momentum toward impeachment had been building among Democrats for months, House Speaker Nancy Pelosi, D-Calif., announced a formal inquiry in September — after a whistleblower complaint about a White House phone call with Ukraine.

In a call with Ukrainian President Volodymyr Zelenskiy, Trump asked for an investigation into a debunked conspiracy theory about the 2016 election and into potential 2020 rival and former Vice President Joe Biden. The White House is also accused of withholding military aid to Ukraine for Trump's personal political gain. Trump maintains that he has done nothing wrong.

Here is the key information you need in order to understand an increasingly complicated affair. Read the latest coverage of the inquiry here.
