I see no evidence of anything more than sworn testimony being given at this stage of the impeachment hearing. My understanding is that evidence doesn't come into play until and unless there is a trial. ETA: For instance, Tim Morrison testified in his secret deposition that he had concerns about Lt Col Vindman's judgment and Morrison's predecessor Fiona Hill (who had been Lt Col Vindman's superior) and other Vindman colleagues had told him that Vindman was, in essence, not to be trusted: stuff about being a leaker, etc. Morrison was one of 2 witnesses selected by Republicans to give open testimony on Tuesday, in the afternoon. ....Vindman, who appeared on Tuesday morning to give his open testimony, was asked by Republican Rep Jim Jordan to respond to Morrison's earlier secret testimony about him . Here's the Q&A on that between Jordan & Vindman: Note: Ms Hill's written evaluation of Lt Col Vindman in July of this year, which Vindman read out when responding to Rep Jordan, was entered into the records. Presumably, this will be used later on as evidence that Morrison lied under oath about what Ms Hill had told him about Lt Col Vindman.
