investigator jose paglieri. >> reporter: this investigation extends to looking at potential investigation into a computer server in russia belonging to a russian bank and a computer server in the united states used by the trump organization. what's so odd is that this russian bank repeatedly looked up the internet address of a computer server in the u.s. used by the trump organization. in tech terms, that's the equivalent of looking up someone's phone number over and over again. while there isn't necessarily the phone call that usually indicates an intention to communicate. that's the information we got from several computer scientists we spoke to. a group of these scientists who obtained these computer records were puzzled as to why in the world was the russian bank doing this. was it trying to send e-mail to the trump organization, some other communication? these scientists couldn't tell.
