March 5, 2015: Questions surround Clinton’s possible use of instant messages on her unsecure BlackBerry.

BlackBerrys from Clinton’s time as secretary of state can be used for instant messages as well as emails. Bloomberg reports that Clinton’s “top aides frequently used instant text messages to talk with each other, a form of communication that isn’t captured or archived by the State Department. It is not clear whether Clinton herself used her BlackBerry’s instant message service, as her aides did.” (Bloomberg News, 3/5/2015)
