Democratic presidential candidate Hillary Clinton’s campaign has confirmed emails on the private server she used while she was secretary of state contain material that is now classified. Clinton has repeatedly said she did not receive material marked classified. Her campaign says the material was classified retroactively, making Clinton the “passive recipient of unwitting information that subsequently became deemed as classified.” Meanwhile, a newly publicized letter from Clinton’s attorney confirms her emails and all other data on her computer server were wiped clean before it was handed over to federal officials.
