Beautiful setting hen Helsinki for this summit which is goi to take place tomorrow at a 1:00 p.m.astern Tim that's when they're to meet. In this presidential palace of ink which is right be me there, thellow building with the white columns, we're here broading from aoaon heinr. The city hall is right behind me. Everng set to ke place Tomo, as I sai a 1:00.m. Stn. Vladimir Putin will get here tomorrow morning. Of our he's the world P tonight. Rge, this meeting comes just after Robert Mueller's indictmef 12 of pun' intelligence officials. The timing is really remarkable. What impact is this going to on the summit? Remarkable, Jon. It has to be intentional. I mean, special unsel, I rod rosenein, te deputy attorney general fr said it W determined by when they hae evidence in PLAC but clearly they could have decided to put this off until afr the summit if they chose to do that. Th wasthey chose to do this before the meeting with presideutin and T trump. I in order to raise stakes of the meeting and, in , put presren president trump to make sure he makes this front and center in his meeting with Vladimir Putin tomorrow. But we saw, Jon, over the course of last week, we know that president trump was briefed on is by rod Rosenstein last Monday and after that fig, evenfter knowing the 12 member of vladim Putin's militantelligence were going toin saw him ref to this as aged witch-nt over the crse of lt week and give somewhat dismissive answers about he was going to press this in his ING with Vladimir Putin. I think this indictment means the presidwill have press itard. I mean, there will be more essure on M O that. As you know, Jon, because of thndictment,here's been lot ofressure on president trump to cancel this meeting, not Toth the summit and Democrats have called on that. En senatorohn McCain said to do that if he's not willing to hvladimir pin accountable.clearly the white house is not going to lis tth vice. They're going to go forward with the meeting tomorr we will see how hasident trump presses on this issue. What they about it afterwards. What's your read on this sum? There's been a suggestion this is a summit that Putin wanted. The president has sahat it's something both men nt what does president trump want aplish here Well, clearly the prent ted this MM he's been pushins staff fo months to get this on the table. Peally afteris meeting with Kim Jong-un which he thought was quite successful and ink that the president mind at least, that meeting is the template for his meeting P P. He deloped thiersona relatiippresident but you've seen already now in the wakethis indicent the president lowering expectations for the meeting, sg he hopes some good will come of it. Hos there won't be much harm coming outit. Here's what's not going to happen in theting, Vladimir Putin is not going to confess to meddling in our election president trump is not going beblto lift stations or T accept president putinenials inhe way that he has in the past. I think going to be very difficult for him to do . So most likely you'll each side sticking to their position and agreeing to disagree and perhaps agreeing to have furthermeetings the future. I think what a lot of preside trump's crs fear is that somehow coming into the meeting whh we know Vladimir Putin has prepared well for, there's been wheparations O therican side, that somehow Vladimir Putin will maneuver the ident intoccepting O appearing to accept run positions on hot button issues not onlythe meddli into our election but other issues like th kea and the sanctions in crimea. George, given what we've seen so far othpresident'trip, ur allies have reason to be apprehensive about what he will agree thn he meets with Putin? Well, we knhey are, J. Step Backe for a second. We know it's been a loerm goal of Vladimir Putin to divide usrom our allies. There S idence of at last week. We nownow that a little over hurt hryhelp elect Donald Trump. Ld trump W elected president, and now he's getting this meeting with thes of the United States. That in itself is a victory adimir put. How president trump handles inrrow will determine whether that victory stands. Fcing, georgethank you for joining us. 'Ltalk to yoagain soon.
