January 21, 2009—February 1, 2013: Clinton may regularly carry two mobile devices at once, although she will later claim otherwise.

In March 2015, after it becomes public knowledge that Clinton exclusively used a private email account for all her email usage, she will claim she did this for “convenience,” so she wouldn’t have to carry two personal devices at once.

However, in 2016, Justin Cooper, an aide to Bill Clinton who helps manage the Clinton private server, will claim otherwise. In an FBI interview, “Cooper stated that he was aware of Clinton using a second mobile phone number. Cooper indicated Clinton usually carried a flip phone along with her BlackBerry because it was more comfortable for communication and Clinton was able to use her BlackBerry while talking on the flip phone.”

However, in Clinton’s 2016 FBI interview, “she did not recall using a flip phone during her tenure [as secretary of state], only during her service in the Senate.” In their FBI interviews, Clinton’s aides Huma Abedin and Cheryl Mills “advised they were unaware of Clinton ever using a cellular phone other than the BlackBerry.”

According to FBI investigators, Clinton has “two known phone numbers… which potentially were used to send emails using Clinton’s clintonemail.com email addresses.” One is associated with her BlackBerry usage. Toll records associated with the other phone number “indicate the number was consistently used for phone calls in 2009 and then used sporadically through the duration of Clinton’s tenure and the years following. Records also showed that no BlackBerry devices were associated with this phone number.” (Federal Bureau of Investigation, 9/2/2016)
