Hillary Clinton has said that the arrangement of her private e-mail system while she was the US secretary of state was a mistake and that she was "sorry" for it.
According to The Washington Post, Clinton's statement came a day after she refused to apologise for her use of a private e-mail system.
Clinton's private e-mail system arrangement mingled her work and personal communications, keeping them outside the regular State Department e-mail system.
She said that she was sorry for confusing people, but insisted that she had done nothing wrong and what she did "was allowed".
