Did the attackers in Benghazi get their hands on valuable information? Catherine Herridge reported the latest this morning on computers that were stolen from the U.S. consulate during the 2012 terror attack that killed Amb. Chris Stevens and three others.

The State Department maintains no classified information was lost, but sources tell Fox News the information on the computers was "extremely valuable."

Former CIA officer Charles Faddis said the computers would have had a "tremendous amount of information" about who was in contact with the consulate and the activities of U.S. personnel there. Herridge said a source confirmed that the computers had access to a top-secret network used by the State and Defense Departments to transmit classified information.

State Department spokeswoman Marie Harf said any computers containing classified information were removed. But Herridge pointed out that the statement appears to conflict with information in Hillary Clinton's book, "Hard Choices."

Writing about the inadequate security at the compound, the former secretary of state said "there was no classified processing at the diplomatic compound in Benghazi."
