Hundreds of times, despite Clinton’s indignant insistence that she never sent or received classified information, the State Department has had to concede that her e-mails must be redacted or withheld from public disclosure because they contain information that is patently classified. But this is not a concession the administration is willing to make regarding Obama’s e-mails.

That is why, as I argued in February, Obama is trying to get away with the vaporous claim that presidential communications must be kept confidential. He does not want to say “executive privilege” because that sounds too much like Nixon. More important, the only other alternative is to designate the e-mails as classified. That would be tantamount to an admission that Obama engaged in the same violation of law as Clinton.

Again, this is why the prosecution of Mrs. Clinton never had a chance of happening. It also explains why, in his public statements about the matter, Obama insisted that Clinton’s e-mailing of classified information did not harm national security. It is why Obama, in stark contrast to his aforementioned executive order, made public statements pooh-poohing the fact that federal law forbids the mishandling of any intelligence secret. (“There’s classified, and then there’s classified,” he said, so cavalierly.) He had to take this position because he had himself effectively endorsed the practice of high-level communications through non-secure channels.

This is also why the Justice Department and the FBI effectively rewrote the relevant criminal statute in order to avoid applying it to Clinton. In his public statements about Clinton, Obama has stressed that she is an exemplary public servant who would never intentionally harm the United States. In rationalizing their decision not to indict Clinton, Justice Department officials (in leaks to the Washington Post) and the FBI director (in his press conference and congressional testimony) similarly stressed the lack of proof that she intended to harm the United States.
