The approximately 7,000 pages of Hillary Clinton emails released late Monday included messages ranging from U.S. efforts to stop Wikileaks disclosures to a Clinton request for help learning to use her new "hPad."
But it is what was not in the Clinton email dump that may be most important.
Approximately 150 of the emails released have information redacted because it has now been deemed to require classification, the State Department said Monday.
The information was not identified as classified when Clinton sent or received the emails.
State Department Deputy Spokesman Mark Toner said this most recent release will meet a federal court requirement that 25 percent of Clinton's emails from her private server be released by the end of August.
Some of the most noteworthy exchanges include:
A State Department official also confirms that the approximately 150 emails that are being upgraded and subsequently classified are all at the "confidential" level — the lowest level of classification.
Newly classified emails include correspondence Clinton had with an aide about an Iran speech she delivered at American University in 2010, and another from the minister counselor for public affairs in Pakistan with the subject "Facebook Freed in Pakistan."
None are "Top Secret" as were two of the emails released last month.
In order for the emails to be released, the team from the intelligence agencies, FBI and State must agree on what should be redacted for reasons of privacy or national security and whether the emails should be classified.
In general, the Inspector General from the intelligence agencies has been demanding more classification than the State Department. Earlier this month, the State Department appealed the Inspector General's decisions to Director of National Intelligence General James Clapper.
The FBI has a team studying the emails to determine whether they were handled securely as is required by law. At this stage, it is not a criminal investigation.
But opponents of the Democratic presidential frontrunner have been quick to point to the redactions as proof Clinton sent and received sensitive information on her email server.
"Hillary Clinton's reckless attempt to skirt transparency laws put sensitive information and our national security at risk," Republican National Committee chair Reince Priebus said in a statement.
