On Tuesday, MSNBC's Rachel Maddow discussed President Donald Trump's supposed second, undisclosed hour-long meeting with Russian President Vladimir Putin at the G20. Maddow spoke with Ian Bremmer, the founder of the "Eurasia Group" regarding this encounter: IAN BREMMER: I got my PhD at Stanford almost 20 years ago now, so I'm getting a little grey. And it is the world's largest risk consultancy, so its a company of political scientists who look how politics affect markets all over the world. RACHEL MADDOW:: Ok, political risk consultancy. How did you come to know about this second meeting between President Trump and President Putin that the White House had never discussed? IAN BREMMER: I don't want to tell you who directly told me, but I know this is the meeting of the priniciples, so its the G20 heads of state and their spouses, most of them were in attendance. It was a very long dinner almost three and a half hours. I know a lot of the people in that group. And many of them including all of America's principle allies they found it remarkable, they were concerned by it, it was noteworthy, and so it got out. And I personally was surprised that there was no read out on it, whatsoever after the meeting happened, and so it was a consequence I felt… Especially because Trump himself had so much talk about what was and what was not discussed in the broader, formal meeting, in that two hour meeting you just spoke about. Did they talk about sanctions, did they, talk about the hacks, did he push them, did he not, Ukraine all of that. I mean none of that really matters if they then had an hour one on one at dinner with only the Russian translator. We have no idea what was in that conversation… So I don't know if we should call it a meeting, what we should do was say it was a dinner. The dinner was three and a half hours long, very long, not everyone that was supposed to attend actually showed up, there was a number of empty seats and about halfway through the dinner Trump gets up, goes around the table, sits down next to Putin and begins this conversation. Everyone that was there, this was in all full view, of all of these heads of state and their spouses, and it was very animated, it was extremely friendly, there was certainly a lot of hand motion going on between the two leaders, the two presidents. But no one knows what they, they were out of earshot, so unless the Russian translator has a tape and I think there's probably reasonable likelihood that he does, then nobody else is going to have a read out of this meeting.
