in a lot of different areas, there are a lot of issues about donald trump and his organizations finances. his personal finances, his business finances, and they do overlap to some degree with questions about russia. >> when i talked to trump supporters, they say this isn't true, there's nothing there, it's a witch hunt and others who acknowledge that some of this might be true don't seem to care. why do you think that is? >> well, i think we live in a highly tribalized moment of politics, where people who want to support trump listen to what he says, and if he says it's a witch hunt they believe it's a witch hunt. and that's not everybody, that's -- you know, some percentage of the public. i think there are americans out there who when mueller brings out indictments they support his investigation and they're curious to see what details he has. >> david, we have a lot to get to tonight, thank you so much for taking time to speak to us.
