New documents obtained by Judicial Watch and made public Monday show that then-Secretary of State Hillary Clinton and other senior officials under President Obama were given intelligence within hours of the Sept. 11, 2012, Benghazi attack describing how it had been planned at least 10 days in advance “to kill as many Americans as possible.”

A heavily redacted copy of a Sept. 12, 2012, Defense Intelligence Agency memo to Clinton, then Secretary of Defense Leon Panetta, the White House National Security Council and the Joint Chiefs of Staff said “the attack was planned 10 or more days prior on approximately 01 September 2012. The intention was to attack the consulate and to kill as many Americans as possible to seek revenge for U.S. killing of Aboyahiye ((ALALIBY)) in Pakistan and in memorial of the 11 September 2001 atacks on the World Trade Center buildings.”
