For weeks now, Democratic members of Congress, career State Department and National Security Council experts and their allies in the media suggest questions about Joe Biden and a Ukrainian gas company and Ukraine meddling in the 2016 election were nothing more than debunked conspiracy theories.

Here is a detailed timeline of key events in the Ukraine scandal, complete with the corroborating evidence. You make your own judgement as to what happened.
