Burnt vehicle after attack at US Consulate that killed US Ambassador to Libya Chris Stevens, Benghazi, Libya/AP
A new report on this past September's attack on the U-S Consulate in Benghazi is blaming State Department heads and its Bureau of Diplomatic Security.
The independent investigation found security "inadequate."
It also said there was no protest before the attack that left Ambassador Chris Stevens and three other Americans dead.
It goes on to say the attack was "unanticipated."
Senior management "does not come out well at all," a source says, as the report blames "management deficiencies."
Secretary of State Hillary Clinton wrote a letter to members of Congress that will accompany the report being sent to lawmakers on Capitol Hill.
