<P> On March 10, 2015, while attending a conference at the headquarters of the United Nations in Manhattan, Clinton spoke with reporters for about 20 minutes . Clinton said she had used a private email for convenience, "because I thought it would be easier to carry just one device for my work and for my personal emails instead of two ." It was later determined that Clinton had used both an iPad and a BlackBerry while Secretary of State . </P> <P> Clinton turned over copies of 30,000 State Department business - related emails from her private server that belonged in the public domain; she later explained that she instructed her lawyer to err on the side of disclosure, turning over any emails that might be work - related . Her aides subsequently deleted about 31,000 emails from the server dated during the same time period that Clinton regarded as personal and private . State Department employees do have the right to delete personal emails . </P> <P> Clinton has used humor to try to shrug off the scandals . In August 2015, when asked by a reporter whether she had "wiped" her server, Clinton laughed and said: "What? Like with a cloth or something? I don't know how it works digitally at all ." In September 2015, Clinton was asked in an interview with Jimmy Fallon on The Tonight Show about the content of the emails . She laughed it off, saying there was nothing interesting and joking that she was offended people found her emails' boring' . </P> <P> Clinton's responses to the question, made during her presidential campaign, evolved over time . </P>
