learned through news reports he was arrested by the fsb, the russian state security agency, formerly known as the kgb. he was reportedly arrested during an espionage operation, but the kremlin has not elaborated on what exactly that means. for the latest, i'm joined by hans nichols at the white house. not a lot of information right now, but there are questions of whether his arrest is for political purposes more than anything else. >> that's the question on this. why was he apprehended when he apparently was acting like a tourist, according to his brother, showing a friend around the kremlin? why was he arrested? and in the past when spies have been arrested inside of russia, they've been immediately exported, immediately expelled. that isn't the case here. so there are a lot of questions that we still need to sort through. the family is concerned about his well being because they haven't heard from him. they do say he's well equipped to handle this situation because he had experience in law enforcement. he was a former marine. he got out as a staff sergeant.
