The FBI agents or officials who were evaluating the emails on Hillary Clinton’s private email server didn’t seem to notice the emails marked with a “C” noting that they were classified, which would make Clinton’s claims to the FBI false and leave room for criminal charges of endangering national security, reports The Daily Caller.

The Intelligence Community Inspector General is the one who finally spotted these “C” after looking at documents regarding the emails.

What the Inspector general spotted was on the texts between FBI agent Peter Strzok and his mistress, FBI lawyer Lisa Page, revealed, “Holy cow,” Strzok wrote, “if the FBI missed this, what else was missed?”

“Remind me to tell you to flag for Andy [redacted] emails we (actually ICIG) found that have portion marks (C) on a couple of paras. DoJ was Very Concerned about this,” he wrote.

“Found on the 30k [emails] provided to State originally. No one noticed. It cuts against ‘I never sent or received anything marked classified,’” he wrote, referring to statements by Clinton downplaying the danger of her email practices.

More of the in-depth investigation considered whether Clinton and her aides emailed materials that were of classified nature were not marked as such and made it harder to determine what the emails were comprised of.

The exchange occurred on June 12, 2016. FBI Director Jim Comey disclosed the findings of marked-classified emails to the House on July 7.

“I cannot overstate to you the sense of urgency about wanting to logically and effectively conclude this investigation,” Comey said.

The ommission allowed Clinton to repeatedly and prominently state that she had “never received nor sent any material that was marked classified,” on her private email server while Secretary of State.

She even said so at major debates, and because the FBI hadn’t caught the letter (C), and therefore never stated its findings, PolitiFact rated the claim “Half True.”

When the FBI belatedly noticed and relayed the truth, the fact-checking site said: “Now we know it’s just plain wrong.”

Clinton decided to print out 55,000 pages instead of providing the State Department with her emails in their digital format, a technique sometimes used by lawyers to make searches harder for their opponents.

The search isn’t as simple as just CTRL-F search for “C,” because the State had to re-digitize the forms with Optical Character Recognition, which can get tripped up on symbols, perhaps interpreting it as something like “[C]” or a copyright symbol. Nonetheless, the classified marker always appears at the beginning of a paragraph and is visually distinct.

The comments come from 500 pages of texts released Wednesday by Senate investigators.
