According to Taylor's opening statement, he was on a conference/video call where OMB staff told him that the aid to Ukraine was on hold at the direction of President Trump. So the next step is to depose the OMB staff member who was on that call and see if she verifies that account and if she had documentation of that order. If she was given that order by her supervisor (which is what Taylor said she claimed), then they will depose that OMB supervisor and so on.You didn't read the statement did you? It was filled with I believe, I heard, I think. That is an opinion and hearsay. More so Sondland is needed to corroborate the testimony which he has yet to do.
I'm surprised you're this clueless when it comes to how investigations work. You seem to be under the impression that when someone says "Person X told me this", everything stops there and we just take that person's word for it.
