It is pretty clear by setting up her own server as we reported earlier, that she was in fact ‘willfully concealing and removing’ records.
Via National Review:
But Mrs. Clinton did something here that went well beyond occasional or incidental use of private e-mail accounts. She eschewed the use of an official account entirely, and deliberately established a private e-mail account, apparently maintained on a server in the Clintons’ New York home. As a result, her e-mails were at no time during her tenure in office subject to the Federal Records Act. (She provided some of the e-mails only after she left office, and only when the Department of State asked for them back.) As our friends at Judicial Watch will no doubt remind everyone, there were plenty of Freedom of Information Act requests that would have implicated her e-mails. But they were never searched, even though a reasonable search of all responsive federal records must be made in response to FOIA requests. And the records would have been relevant to congressional inquiries as well, including continuing investigations of the Benghazi attacks.
Why does that matter? Well, a federal criminal law makes it a felony when any custodian of official government records “willfully and unlawfully conceals, removes, mutilates, obliterates, falsifies, or destroys the same.” The crime is punishable by up to three years in prison. And interestingly, Congress felt strongly enough about the crime that it included the unusual provision that the perpetrator shall “forfeit his office and be disqualified from holding any office under the United States.”
