>> all right, miguel, thank you. tonight, as hillary clinton campaigns in nevada, nbc news has learned the nba has begun its analysis of the private e-mail server she used while serving as secretary of state. and we've also learned this week a federal judge in washington is set to hold a hearing on another issue touching on this e-mail controversy surrounding a well-known member of clinton's inner circle. our justice correspondent pete williams has late details. >> reporter: the fbi's forensics experts are now examining the server once located in hillary clinton's new york home, the device that hosted her private e-mail account. two sources familiar with the process say analysts are optimistic they can recover at least some data even though they've determined as was previously disclosed it was wiped clean when the account was deactivated. the fbi is examining whether any government secrets were improperly sent or received on the private server which was not a classified system. >> it was never designed to be secure. it was designed to be a way of sharing information, not protecting information from being shared. >> i do want to be the champion -- >> reporter: the e-mails have been a stubborn political issue, a nearly daily distraction for her. just yesterday the state department said 305 e-mails have been flagged for further review to see if they contain classified information. on thursday a federal judge holds a hearing on a lawsuit touching on the e-mail controversy involving houma abedin, a key clinton campaign adviser constantly at the k7bd's side. she was also a top aide to the secretary of state and had an account on the server. a watchdog group that sued to get details of abedin's contract has expanded its lawsuit demanding a search of the clinton e-mails for answers. >> i think they are dragging their feet. i think they are engaged in some form of gamesmanship, legal gamesmanship, and they're being less than frank and forthcoming. >> reporter: she was asked today if she regrets setting up the private server. >> i do now. in retrospect what was supposed to be convenient has turned out to be anything but convenient. >> reporter: and mrs. clinton says even if she had used the state department e-mail system, not her own, all the material would have to be reviewed anyway before releasing it publicly and she said that would raise the same kinds of questions about whether some of it should have been classified. lester?
