The Democratic-led House of Representatives is pursuing an impeachment inquiry into President Trump. Here is the key information you need in order to understand an increasingly complicated affair.
First, some background: While momentum toward impeachment had been building among Democrats for months, House Speaker Nancy Pelosi, D-Calif., announced an inquiry in September — after a whistleblower complaint about a White House phone call with Ukraine. The House formalized the inquiry and outlined their path forward with a vote on Oct. 28. The first open hearing in the inquiry is scheduled for Nov. 13.
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.
