quid pro quo. the idea that the money was released because they knew there was an investigation going to be happening. >> right. and in some ways there was already evidence of this. we know that the democrats had announced an investigation of ukraine matters on september 9th, two days before the aid gets released, but this tells you even more that the president and his team was aware at least in a broad way of what the whistle-blower had concerns about. and so we now know a new element of the time line just gets introduced, usually these things are well-settled by the time utalk about drafting articles of impeachment. so very fast moving situation. >> let's talk about the articles of impeachment. something you wrote tonight two articles are virtually guaranteed to show up as features of impeachment against the president but that democrats are divided on whether to involve matters related to russia and the mueller investigation into this. tell me a bit about the dispute. >> right, so the ukraine investigation clearly honed in on the abuse of power argument.
