brought against clinton. the fbi stumbled on them while conducting an investigation of abed abedin s estranged husband, anthony wiener. he was under investigation for exchanging sexually explicit messages with an underaged girl. why did all of this become here on friday? law enforcement officials tell me that investigators spent months doing a lot of work trying to figure out how big of a deal this was. technical experts were cataloging the ez mails, analyzing the met data to determine that a significant number of the e-mails went through the clinton server. officials tell me they saw enough in the e-mails to know there may be classified information in them and some may not have been reviewed by fbi agents before. they were constrained that they were operating under the warrant limited to the wiener sexual case. they re bringing back the agents and trying to do this as quickly
