this is who they want to hear from. the whistleblower, hunter biden, kurt volker, the former special envoy to ukraine, david hail, a top state department official, tim morrison, nelly ore, the wife of bruce ore and alexandria cha li chalupa. >> we have heard from three of four or those witnesses, prospective witnesses in the deposition process. personally speaking for myself, i wouldn't have any problem with them. what we're not going to do as adam schiff said is allow them to sort of revisit these crazy already debunked conspiracy theories about the bidens and ukraine. or to try to out the whistleblower. we're not going to be party to that. we're not going to give them a platform to do that. >> but you see there is some negotiation to be had over this
