lawyer, natalie veselnitskaya, who is an agent for vladimir putin, went in with an ask. the ask was to repeal the sanctions. now, the russians aren't stupid. they don't ask for something unless they have something to offer. we don't know exactly what she was offering, there is some allegations that she was offering dirt on hillary clinton. she might have been offering some other stuff. what we don't know is what she was offering and if that was accepted. that's the subject of the mueller investigation. >> exactly. there is an e-mail documentation of that, donald trump jr. believed she was offering dirt on hillary clinton. in the midst of this, as you know, president trump seems very willing to have yet another summit with vladimir putin a little more than a week after a summit that even republicans panned as disastrous. what is putin trying to do here by being open to another summit with president trump? what advantage is he seeking? >> well, let's just put this in very simple perspective.
