A year before Hillary Clinton apparently asked one of her top aides to remove the classification markings from a sensitive document and send it to her over an unsecured network, she pushed the same aide to remove a different document from the State Department's classified system and email it to her without markings.

The pair of email exchanges hint at the pattern of disregard for record-keeping practices that landed Clinton and her staff under investigation by the FBI this summer for potentially mishandling classified information.

The more recent email, written in June 2011, was made public Friday by the State Department in an overnight dump of documents lacking subject fields or other distinguishing headers.

In that email, Clinton asked Jake Sullivan, one of her top advisers, to remove the markings from a set of seemingly classified talking points and send it to her "nonsecure" after State Department staff were too slow to send the document over a secure fax line.

But in Feb. 2010, Clinton had made a similar demand of Sullivan after drafts of a diplomatic statement were made on the agency's classified network.

"It's a public statement! Just email it," Clinton wrote after Sullivan informed her of the delay she would face in receiving the document until it was converted to an unclassified format.

"Trust me, I share your exasperation," Sullivan replied. "But until ops converts it to the unclassified email system, there is no physical way for me to email it. I can't even access it."
