For over 3 days already. With complete silence everywhere. He didn't announce visit or any events, purpose of visit or whatever. Was noticed in Bolshoi Theater looking Spartak balet.
Weird. :) Could he be used as kind of messenger or negotiator by those who he represents in media?
Yes. And looks like he found family happiness here. He got Russian citizenship, lives in Moscow with his wife (also American) who gave birth to two children here, he got some weight and looks happy. Rumors are he works as sysadmin or programmer in one of large Russian IT companies. Also he gives some interviews from time to time and write a new book. For obvious reasons nobody will disclose his exact address and palce of work.
I'm glad for him. That's my guess as to why Tucker is there. Although I can't decide if a video interview would be safer.
