WASHINGTON: Hillary Clinton defended her use of a private email server for official correspondence while US secretary of state on Thursday, insisting her actions were no different than that of her predecessors. One day after the release of a critical State Department investigation faulting her use of personal email for government business, Clinton vowed that she would not allow the issue to dog her campaign. “There may be reports that come out, but nothing has changed,” the Democratic White House frontrunner told CNN. “It’s the same story. Just like previous secretaries of state, I used a personal email. Many people did. It was not at all unprecedented.” In a subsequent interview with the television network, she repeated her acknowledgement that she made a “mistake,” and that looking back she would have avoided such actions. Clinton’s use of a private server for official correspondence first came to light in 2015 during Republican-led congressional investigations into her handling of a militant attack on the US mission in Benghazi, Libya. The assault in 2012 left the US ambassador and three other Americans dead.
