heard trump ask the ambassador about the status of the investigation during a cell phone conversation at a restaurant. set to testify behind closed doors. republicans can't use the made up defense this is hearsay. >> they have been trying to move the goal post. the claim was about process. that we want these witnesses to testify publicly. now they're testifying publicly. now the problem is they didn't talk to the president directly. as if the president really needs to micro manage every person in the executive branch who is following his orders. and now of course it's that -- something new. i don't know what. and for presumably when this person testifies and said i heard this on the call. they'll claim, the discussion wasn't directed at you. even that argument of course is risky. bolton could at some point come forward. if he decides to comply with the subpoena. we'll wait.
